This is the input signal for the average current regulation in the current loop. It is also fed to the peak current limitation block. During power up time, high inrush currents cause high negative voltage drop at R1, driving currents out of pin 3 which could be beyond the absolute maximum ratings. Therefore a series resistor (R2) of around 220W is recommended in order to limit this current into the IC. FREQ (Frequency Setting) This pin allows the setting of the operating switching frequency by connecting a resistor to ground. The frequency range is from 50kHz to 250kHz.

The reference voltage for this pin is 3V. VCOMP (Voltage Loop Compensation) This pin provides the compensation of the output voltage loop with a compensation network to ground (see Figure 2). This also gives the soft start function which controls an increasing AC input current during start-up. VCC (Power Supply) The VCC pin is the positive supply of the IC and should be connected to an external auxiliary supply. The operating range is between 11V and 26V. The turn-on threshold is at 11.8V and under voltage occurs at 11V. There is no internal clamp for a limitation of the power supply. Pin Configuration (top view) GATE The GATE pin is the output of the internal driver stage, which has a capability of 1.5A instantaneous source and 2.0A instantaneous sink current. Its gate drive voltage is clamped at 15V (typically). Pin Functionality GND (Ground) The ground potential of the IC.

The IC will then be consuming typically 300mA, whereas consuming 13mA during normal operation. The IC can be turned off and forced into standby mode by pulling down the voltage at pin 6 (VSENSE) to lower than 0.6V. The current consumption is reduced to 300µA in this mode. The ICE2PCS01/G is a 8 pin control IC for power factor correction converters. It comes in both DIP and DSO packages and is suitable for wide range line input applications from 85 to 265 VAC. The IC supports converters in boost topology and it operates in continuous conduction mode (CCM) with average current control. The IC operates with a cascaded control; the inner current loop and the outer voltage loop. The inner current loop of the IC controls the sinusoidal profile for the average input current. It uses the dependency of the PWM duty cycle on the line input voltage to determine the corresponding input current. This means the average input current follows the input voltage as long as the device operates in CCM. Under light load condition, depending on the choke inductance, the system may enter into discontinuous conduction mode (DCM). In DCM, the average current waveform will be distorted but the resultant harmonics are still low enough to meet the Class D requirement of IEC 10003-2. The outer voltage loop controls the output bus voltage. Depending on the load condition, OTA1 establishes an appropriate voltage at VCOMP pin which controls the amplitude of the average input current. The IC is equipped with various protection features to ensure safe operating condition for both the system and device. Important protection features are namely Open-Loop protection, Current Limitation and Output Over-voltage Protection. 3.3 Start-up Figure 4 shows the operation of voltage loop’s OTA1 during startup. The VCOMP pin is pull internally to ground via switch S1 during UVLO and other fault conditions (see later section on “System Protection”). During power up when VOUT is less than 83% of the rated level, OTA1 sources an output current, maximum 30mA, into the compensation network at pin 5 (VCOMP) causing the voltage at this pin to rise linearly. This results in a controlled linear increase of the input current from 0A thus reducing the stress on the external component. VSENSE R4 x V OUT ) R3 + R4 ( OTA1 3V VCOMP S1 3.2 R6 Power Supply C4 An internal under voltage lockout (UVLO) block monitors the VCC power supply. As soon as it exceeds 11.8V and the voltage at pin 6 (VSENSE) is >0.6V, the IC begins operating its gate drive and performs its Startup as shown in Figure 3. . (VVSENSE > 0.6 V) (VVSENSE < 0.6 V) p ro tec t Figure 4 C5 IC E 2 P C S 0 1 /G Startup Circuit As VOUT has not reached within 5% from the rated value, VCOMP voltage is level-shifted by the window detect block as shown in Figure 5, to ensure there is fast boost up of the output voltage. When VOUT approaches its rated value, OTA1’s sourcing current drops and the level shift of the window detect block is removed. The normal voltage loop then takes control.

A further increase in the inductor current, which results in a lower ISENSE voltage, will activate the Soft Over Current Control (SOC). This is a soft control as it does not directly switch off the gate drive. It acts on the nonlinear gain block to result in a reduced PWM duty cycle.

In this case, most of the blocks within the IC will be shutdown. It is implemented using comparator C3 with a threshold of 0.6V as shown in the IC block diagram in Figure 2. POUT(max) Normal Operation SOC 3.4.4 Over-Voltage Protection (OVP) Whenever VOUT exceeds the rated value by 5%, the over-voltage protection OVP is active as shown in Figure 6. This is implemented by sensing the voltage at pin VSENSE with respect to a reference voltage of 3.15V. A VSENSE voltage higher than 3.15V will immediately reduce the output duty cycle, bypassing the normal voltage loop control. This results in a lower input power to reduce the output voltage VOUT. A VSENSE voltage higher than 3.25V will immediately turn off the gate, thereby preventing damage to bus capacitor.

The pin voltage VFREQ is typically 1.7V. The corresponding capacitor for the oscillator is integrated in the device and the R5/frequency relationship is given at the “Electrical Characteristic” section. The recommended operating frequency range is from 50kHz to 250kHz. As an example, a R5 of 33kW at pin FREQ will set a switching frequency FSW of 136kHz typically. 0.75 P OUT ( max ) = V INMIN ´ ------------------R1 × 2 3.4.2 Peak Current Limit (PCL) The IC provides a cycle by cycle peak current limitation (PCL). It is active when the voltage at pin 3 (ISENSE) reaches -1.04V. This voltage is amplified by OP1 by a factor of -1.43 and connected to comparator C2 with a reference voltage of 1.5V as shown in Figure 9.

The objective of the current loop is to regulate the average inductor current such that it is proportional to the off duty cycle DOFF, and thus to the input voltage VIN. Figure 12 shows the scheme to achieve the objective. 3.6.1 Complete Current Loop The complete system current loop is shown in Figure 11.

The PWM cycle starts with the Gate turn off for a duration of TOFFMIN (250ns typ.) and the ramp is kept discharged. The ramp is then allowed to rise after TOFFMIN expires. The off time of the boost transistor ends at the intersection of the ramp signal and the averaged current waveform. This results in the proportional relationship between the average current and the off duty cycle DOFF. Figure 13 shows the timing diagrams of TOFFMIN and the PWM waveforms. ICE2PCS01/G Figure 11 Complete System Current Loop It consists of the current loop block which averages the voltage at pin ISENSE, resulted from the inductor current flowing across R1. The averaged waveform is compared with an internal ramp in the ramp generator and PWM block. Once the ramp crosses the average waveform, the comparator C1 turns on the driver stage through the PWM logic block. The Nonlinear Gain block defines the amplitude of the inductor current. The following sections describe the functionality of each individual blocks. TOFFMIN 2.5% of T 3.6.2 Current Loop Compensation The compensation of the current loop is done at the ICOMP pin. This is the OTA2 output and a capacitor C3 has to be installed at this node to ground (see Figure 11). Under normal mode of operation, this pin gives a voltage which is proportional to the averaged inductor current. This pin is internally shorted to 4.2V in the event of IC shuts down when OLP and UVLO occur. PWM cycle VCREF(1) VRAMP ramp released PWM 3.6.3 Pulse Width Modulation (PWM) The IC employs an average current control scheme in continuous conduction mode (CCM) to achieve the power factor correction.

The input of this block is the 10 22 March 2010 CCM-PFC ICE2PCS01/G Functional Description voltage at pin VCOMP. This block has been designed to support the wide input voltage range (85-265VAC). 3.7 From Full-wave Retifier PWM Logic The PWM logic block prioritizes the control input signals and generates the final logic signal to turn on the driver stage. The speed of the logic gates in this block, together with the width of the reset pulse TOFFMIN, are designed to meet a maximum duty cycle DMAX of 95% at the GATE output under 136kHz of operation. In case of high input currents which result in Peak Current Limitation, the GATE will be turned off immediately and maintained in off state for the current PWM cycle. The signal Toffmin resets (highest priority, overriding other input signals) both the current limit latch and the PWM on latch as illustrated in Figure 14. Peak Current Limit Current Loop PWM on signal Current Limit Latch Q S L1 R Gate Driver Nonlinear Gain Av(IIN) OTA1 3V VSENSE t HIGH = turn GATE on VCOMP R6 C4 C5 Q Voltage Loop 3.8.2 Enhanced Dynamic Response Due to the low frequency bandwidth of the voltage loop, the dynamic response is slow and in the range of about several 10ms. This may cause additional stress to the bus capacitor and the switching transistor of the PFC in the event of heavy load changes. The IC provides therefore a “window detector” for the feedback voltage VVSENSE at pin 6 (VSENSE). Whenever VVSENSE exceeds the reference value (3V) by +5%, it will act on the nonlinear gain block which in turn affect the gate drive duty cycle directly. This change in duty cycle is bypassing the slow changing VCOMP voltage, thus results in a fast dynamic response of VOUT. PWM Logic Voltage Loop The voltage loop is the outer loop of the cascaded control scheme which controls the PFC output bus voltage VOUT. This loop is closed by the feedback sensing voltage at VSENSE which is a resistive divider tapping from VOUT. The pin VSENSE is the input of OTA1 which has an internal reference of 3V. Figure 15 shows the important blocks of this voltage loop. 3.8.1 Voltage Loop Compensation The compensation of the voltage loop is installed at the VCOMP pin (see Figure 15). This is the output of OTA1 and the compensation must be connected at this pin to ground. The compensation is also responsible for the soft start function which controls an increasing AC input current during start-up.

It has an in-built cross conduction currents protection and a Zener diode Z1 (see Figure 16) to protect the external transistor switch against undesirable over voltages. The maximum voltage at pin 8 (GATE) is typically clamped at 15V. The output is active HIGH and at VCC voltages below the under voltage lockout threshold VCCUVLO, the gate drive is internally pull low to maintain the off state. 11 22 March 2010 CCM-PFC ICE2PCS01/G Functional Description VCC Gate Driver PWM Logic HIGH to turn on LV Z1 External MOS GATE * LV: Level Shift ICE2PCS01/G Figure 16 Gate Driver Version 2.3 12 22 March 2010 CCM-PFC ICE2PCS01/G Electrical Characteristics 4 Electrical Characteristics 4.1 Note: Absolute Maximum Ratings Absolute maximum ratings are defined as ratings, which when being exceeded may lead to destruction of the integrated circuit.
