In standby mode frequency reduction is used to lower the power consumption and support a stable output voltage in this mode. The frequency reduction is limited to 20kHz/21.5 kHz to avoid audible noise. In case of failure modes like open loop, overvoltage or overload due to short circuit the device switches in Auto Restart Mode which is controlled by the internal protection unit. By means of the internal precise peak current limitation, the dimension of the transformer and the secondary diode can be sized lower which leads to more cost effective for the overall system. • • • •

FB (Feedback) The information about the regulation is provided by the FB Pin to the internal Protection Unit and to the internal PWM-Comparator to control the duty cycle. Isense (Current Sense) The Current Sense pin senses the voltage developed on the series resistor inserted in the source of the integrated CoolMOS™. When Isense reaches the internal threshold of the Current Limit Comparator, the Driver output is disabled. By this means the Over Current Detection is realized. Furthermore the current information is provided for the PWM-Comparator to realize the Current Mode. Drain (Drain of integrated CoolMOS™) Pin Drain is the connection to the Drain of the internal CoolMOSTM. VCC (Power supply) This pin is the positive supply of the IC. The operating range is between 8.5V and 21V. To provide overvoltage protection the driver gets disabled when the voltage becomes higher than 16.5V during Start Up Phase. GND (Ground) This pin is the ground of the primary side of the SMPS.

In case the IC is inactive the current consumption is max. 55µA. When the SMPS is plugged to the main line the current through RStart-up charges the external Capacitor CVCC. When VVCC exceeds the on-threshold VCCon=13.5V the internal bias circuit and the voltage reference are switched on. After that the internal bandgap generates a reference voltage VREF=6.5V to supply the internal circuits. To avoid uncontrolled ringing at switch-on a hysteresis is implemented which means that switch-off is only after active mode when Vcc falls below 8.5V. In case of switch-on a Power Up Reset is done by resetting the internal error-latch in the protection unit. When VVCC falls below the off-threshold VCCoff=8.5V the internal reference is switched off and the Power Down reset let T1 discharging the soft-start capacitor CSoft-Start at pin SoftS. Thus it is ensured that at every switch-on the voltage ramp at pin SoftS starts at zero. Version 2.6 Driver t T on t Figure 8 Pulse Width Modulation In case the amplified current sense signal exceeds the FB signal the on-time Ton of the driver is finished by resetting the PWM-Latch (see Figure 8). The primary current is sensed by the external series resistor RSense inserted in the source of the integrated CoolMOS™. By means of Current Mode regulation, the 10 25 Dec 2006 CoolSET™-F2 Functional Description secondary output voltage is insensitive on line variations. Line variation changes the current waveform slope which controls the duty cycle. The external RSense allows an individual adjustment of the maximum source current of the integrated CoolMOS™.

Duty Cycle Soft-Start Comparator PWM Comparator Voltage Ramp FB PWM-Latch Oscillator 0.3V Gate Driver VOSC C1 Gate Driver 20pF x3.65 V1 PWM OP t Figure 10 Voltage Ramp Figure 9 3.2.1 Improved Current Mode Light Load Conditions PWM-OP The input of the PWM-OP is applied over the internal leading edge blanking to the external sense resistor RSense connected to pin Isense. RSense converts the source current into a sense voltage. The sense voltage is amplified with a gain of 3.65 by PWM OP. The output of the PWM-OP is connected to the voltage source V1. The voltage ramp with the superimposed amplified current signal is fed into the positive inputs of the PWMComparator, C5 and the Soft-Start-Comparator. To improve the Current Mode during light load conditions the amplified current ramp of the PWM-OP is superimposed on a voltage ramp, which is built by the switch T2, the voltage source V1 and the 1st order low pass filter composed of R1 and C1(see Figure 9, Figure 10). Every time the oscillator shuts down for max. duty cycle limitation the switch T2 is closed by VOSC. When the oscillator triggers the Gate Driver T2 is opened so that the voltage ramp can start. In case of light load the amplified current ramp is to small to ensure a stable regulation. In that case the Voltage Ramp is a well defined signal for the comparison with the FB-signal. The duty cycle is then controlled by the slope of the Voltage Ramp. By means of the Comparator C5, the Gate Driver is switched-off until the voltage ramp exceeds 0.3V. It allows the duty cycle to be reduced continuously till 0% by decreasing VFB below that threshold. Version 2.6 t 0.8V R1 T2 0.8V FB 0.3V C5 10kΩ t 3.2.2 PWM-Comparator The PWM-Comparator compares the sensed current signal of the integrated CoolMOSTM with the feedback signal VFB (see Figure 11). VFB is created by an external optocoupler or external transistor in combination with the internal pull-up resistor RFB and provides the load information of the feedback circuitry. When the amplified current signal of the integrated CoolMOS™ exceeds the signal VFB the PWMComparator switches off the Gate Driver. 11 25 Dec 2006 CoolSET™-F2 Functional Description pull-up resistor RSoft-Start. The Soft-Start-Comparator compares the voltage at pin SoftS at the negative input with the ramp signal of the PWM-OP at the positive input. When Soft-Start voltage VSoftS is less than Feedback voltage VFB the Soft-Start-Comparator limits the pulse width by resetting the PWM-Latch (see Figure 12). In addition to Start-Up, Soft-Start is also activated at each restart attempt during Auto Restart. By means of the above mentioned CSoft-Start the SoftStart can be defined by the user. The Soft-Start is finished when VSoftS exceeds 5.3V. At that time the Protection Unit is activated by Comparator C4 and senses the FB by Comparator C3 wether the voltage is below 4.8V which means that the voltage on the secondary side of the SMPS is settled. The internal Zener Diode at SoftS has a clamp voltage of 5.6V to prevent the internal circuit from saturation (see Figure 13). 6.5V Soft-Start Comparator RFB FB PWM-Latch PWM Comparator 0.8V Optocoupler PWM OP Isense x3.65 6.5V 5.6V Improved Current Mode Figure 11 3.3 RSoft-Start Error-Latch SoftS 6.5V 5.3V PWM Controlling Soft-Start 4.8V RFB FB VSoftS C4 G2 C3 Clock R Q S Q R Q Gate Driver S Q PWM-Latch 5.6V 5.3V Figure 13 Gate Driver Activation of Protection Unit The Start-Up time TStart-Up within the converter output voltage VOUT is settled must be shorter than the SoftStart Phase TSoft-Start (see Figure 14). TSoft-Start T Soft – Start C Soft – Start = -----------------------------------R Soft – Start × 1.69 t By means of Soft-Start there is an effective minimization of current and voltage stresses on the integrated CoolMOS™, the clamp circuit and the output overshoot and prevents saturation of the transformer during Start-Up. t Figure 12 Power-Up Reset Soft-Start Phase The Soft-Start is realized by the internal pull-up resistor RSoft-Start and the external Capacitor CSoft-Start (see Figure 5). The Soft-Start voltage VSoftS is generated by charging the external capacitor CSoft-Start by the internal Version 2.6 12 25 Dec 2006 CoolSET™-F2 Functional Description VSoftS kHz 100 fOSC 5.3V TSoft-Start VFB 65 21.5 t 1.0 4.8V 1.1 TStart-Up t Start Up Phase 3.4 Oscillator and Frequency Reduction 3.4.1 Oscillator fnorm 100kHz 67kHz fstandby 21.5kHz 20kHz 1.6 1.7 1.8 1.9 2.0 V VFB Frequency Dependence Current Limiting 3.5.1 The oscillator generates a frequency fswitch = 67kHz/ 100kHz. A resistor, a capacitor and a current source and current sink which determine the frequency are integrated. The charging and discharging current of the implemented oscillator capacitor are internally trimmed, in order to achieve a very accurate switching frequency. The ratio of controlled charge to discharge current is adjusted to reach a max. duty cycle limitation of Dmax=0.72. 3.4.2 1.5 There is a cycle by cycle current limiting realized by the Current-Limit Comparator to provide an overcurrent detection. The source current of the integrated CoolMOSTM is sensed via an external sense resistor RSense. By means of RSense the source current is transformed to a sense voltage VSense. When the voltage VSense exceeds the internal threshold voltage Vcsth the Current-Limit-Comparator immediately turns off the gate drive. To prevent the Current Limiting from distortions caused by leading edge spikes a Leading Edge Blanking is integrated at the Current Sense. Furthermore a Propagation Delay Compensation is added to support the immediate shut down of the CoolMOS™ in case of overcurrent. VOUT Figure 14 1.4 ICE2Bxxxx 3.5 t 1.3 ICE2Axxxx Figure 15 VOUT 1.2 Leading Edge Blanking VSense Vcsth tLEB = 220ns Frequency Reduction The frequency of the oscillator is depending on the voltage at pin FB. The dependence is shown in Figure 15. This feature allows a power supply to operate at lower frequency at light loads thus lowering the switching losses while maintaining good cross regulation performance and low output ripple. In case of low power the power consumption of the whole SMPS can now be reduced very effective. The minimal reachable frequency is limited to 20kHz/21.5 kHz to avoid audible noise in any case. Version 2.6 t Figure 16 Leading Edge Blanking Each time when CoolMOS™ is switched on a leading spike is generated due to the primary-side capacitances and secondary-side rectifier reverse recovery time. To avoid a premature termination of the switching pulse this spike is blanked out with a time constant of tLEB = 220ns. During that time the output of 13 25 Dec 2006 CoolSET™-F2 Functional Description the Current-Limit Comparator cannot switch off the gate drive. 3.5.2 The propagation delay compensation is done by means of a dynamic threshold voltage Vcsth (see Figure 18). In case of a steeper slope the switch off of the driver is earlier to compensate the delay. E.g. Ipeak = 0.5A with RSense = 2. Without propagation delay compensation the current sense threshold is set to a static voltage level Vcsth=1V. A current ramp of dI/dt = 0.4A/µs, that means dVSense/dt = 0.8V/µs, and a propagation delay time of i.e. tPropagation Delay =180ns leads then to a Ipeak overshoot of 14.4%. By means of propagation delay compensation the overshoot is only about 2% (see Figure 19). Propagation Delay Compensation In case of overcurrent detection by ILimit the shut down of CoolMOS™ is delayed due to the propagation delay of the circuit. This delay causes an overshoot of the peak current Ipeak which depends on the ratio of dI/dt of the peak current (see Figure 17). .

After setting the PWM-Latch can be reset by the PWMOP, the Soft-Start-Comparator, the Current-LimitComparator, Comparator C3 or the Error-Latch of the Protection Unit. In case of resetting the driver is shut down immediately. dV Sense dI peak - ≤ --------------0 ≤ R Sense× ----------dt dt max. Duty Cycle 3.7 off time Propagation Delay Vcsth t Signal1 Signal2 Dynamic Voltage Threshold Vcsth Version 2.6 Driver The driver-stage drives the gate of the CoolMOS™ and is optimized to minimize EMI and to provide high circuit efficiency. This is done by reducing the switch on slope when reaching the CoolMOS™ threshold. This is achieved by a slope control of the rising edge at the driver’s output (see Figure 20) to the CoolMOS™ gate. Thus the leading switch on spike is minimized. When CoolMOS™ is switched off, the falling shape of the driver is slowed down when reaching 2V to prevent an overshoot below ground. Furthermore the driver circuit is designed to eliminate cross conduction of the output stage. At voltages below the undervoltage lockout threshold VVCCoff the gate drive is active low. t VSense Figure 18 0.4 dVSense dt The overshoot of Signal2 is bigger than of Signal1 due to the steeper rising waveform. A propagation delay compensation is integrated to bound the overshoot dependent on dI/dt of the rising primary current. That means the propagation delay time between exceeding the current sense threshold Vcsth and the switch off of CoolMOS™ is compensated over temperature within a range of at least.

These three failure modes are latched by an Error-Latch. Additional thermal shutdown is latched by the Error-Latch. In case of those failure modes the Error-Latch is set after a blanking time of 5µs and the CoolMOS™ is shut down. That blanking prevents the Error-Latch from distortions caused by spikes during operation mode. 3.8.1 t SoftS t TBurst1 Driver TRestart t Overload / Open Loop with Normal Load VCC 13.5V Figure 21 shows the Auto Restart Mode in case of overload or open loop with normal load. The detection of open loop or overload is provided by the Comparator C3, C4 and the AND-gate G2 (see Figure 22). The detection is activated by C4 when the voltage at pin SoftS exceeds 5.3V. Till this time the IC operates in the Soft-Start Phase. After this phase the comparator C3 can set the Error-Latch in case of open loop or overload which leads the feedback voltage VFB to exceed the threshold of 4.8V. After latching VCC decreases till 8.5V and inactivates the IC. At this time the external Soft-Start capacitor is discharged by the internal transistor T1 due to Power Down Reset. When the IC is inactive VVCC increases till VCCon = 13.5V by charging the Capacitor CVCC by means of the Start-Up Resistor RStart-Up. Then the Error-Latch is reset by Power Up Reset and the external Soft-Start capacitor CSoft-Start is charged by the internal pull-up resistor RSoft-Start. During the Soft-Start Phase which ends when the voltage at pin SoftS exceeds 5.3V the detection of overload and open loop by C3 and G2 is inactive. In this way the Start Up Phase is not detected as an overload. 8.5V t Figure 21 Auto Restart Mode 6.5V Power Up Reset SoftS RSoft-Start CSoft-Start 5.3V C4 T1 4.8V Error-Latch G2 C3 FB RFB 6.5V Figure 22 Version 2.6 15 FB-Detection 25 Dec 2006 CoolSET™-F2 Functional Description But the Soft-Start Phase must be finished within the Start Up Phase to force the voltage at pin FB below the failure detection threshold of 4.8V. 3.8.2 normal operation mode is prevented from overvoltage detection due to varying of VCC concerning the regulation of the converter output.

In that case the IC switches in Auto Restart Mode. Overvoltage Detection VCC 16.5V 13.5V t 8.5V t Figure 23 Auto Restart Mode Figure 23 shows the Auto Restart Mode for open loop and no load condition. In case of this failure mode the converter output voltage increases and also VCC. An additional protection by the comparators C1, C2 and the AND-gate G1 is implemented to consider this failure mode (see Figure 24).The overvoltage detection is provided by Comparator C1 only in the first time during the Soft-Start Phase till the Soft-Start voltage exceeds the threshold of the Comparator C2 at 4.0V and the voltage at pin FB is above 4.8V. When VCC exceeds 16.5V during the overvoltage detection phase C1 can set the Error-Latch and the Burst Phase during Auto Restart Mode is finished earlier. In that case TBurst2 is shorter than TSoft-Start. By means of C2 the Version 2.6 Note: 16 All the values which are mentioned in the functional description are typical.
