FAN6300A / FAN6300H Highly Integrated Quasi-Resonant Current Mode PWM Controller Features Description High-Voltage Startup Low Frequency Operation (below 100 kHz) for FAN6300A High Frequency Operation (up to 190 kHz) for FAN6300H Quasi-Resonant Operation Cycle-by-Cycle Current Limiting Peak-Current-Mode Control Leading-Edge Blanking (LEB) Internal Minimum tOFF Internal 5 ms Soft-Start Over Power Compensation GATE Output Maximum Voltage Auto-Recovery Over-Current Protection(FB Pin) Auto-Recovery Open-Loop Protection(FB Pin) VDD Pin and Output Voltage (DET Pin) OVP Latched Applications The highly integrated FAN6300A/H of PWM controller provides several features to enhance the performance of flyback converters. FAN6300A is applied on quasiresonant flyback converters where maximum operating frequency is below 100 kHz. FAN6300H is suitable for high-frequency operation (up to 190 kHz). A built-in HV startup circuit can provide more startup current to reduce the startup time of the controller. Once the VDD voltage exceeds the turn-on threshold voltage, the HV startup function is disabled immediately to reduce power consumption. An internal valley voltage detector ensures power system operates at quasi-resonant operation over a wide-range of line voltage and any load conditions, as well as reducing switching loss to minimize switching voltage on drain of power MOSFET. To minimize standby power consumption and light-load efficiency, a proprietary green-mode function provides off-time modulation to decrease switching frequency and perform extended valley voltage switching to keep to a minimum switching voltage. The operating frequency is limited by minimum toff time, which is 38 µs to 8 µs in FAN6300A and 13 µs to 3 µs in FAN6300H, so FAN6300H can operate at higher switching frequency than FAN6300A. FAN6300A/H controller also provides many protection functions. Pulse-by-pulse current limiting ensures the fixed-peak current limit level, even when a short circuit occurs. Once an open-circuit failure occurs in the feedback loop, the internal protection circuit disables PWM output immediately. As long as VDD drops below the turn-off threshold voltage, the controller also disables PWM output. The gate output is clamped at 18 V to protect the power MOS from high gate-source voltage conditions. The minimum tOFF time limit prevents the system frequency from being too high. If the DET pin triggers OVP, internal OTP is triggered and the power system enters latch-mode until AC power is removed.

Pin Configuration Pin Definitions Pin # 1 Name DET Description This pin is connected to an auxiliary winding of the transformer via resistors of the divider for the following purposes: - Generates a ZCD signal once the secondary-side switching current falls to zero. - Produces an offset voltage to compensate the threshold voltage of the peak current limit to provide a constant power limit. The offset is generated in accordance with the input voltage when PWM signal is enabled. - Detects the valley voltage of the switching waveform to achieve the valley voltage switching and minimize the switching losses. A voltage comparator and a 2.5 V reference voltage develop a output OVP protection. The ratio of the divider decides what output voltage to stop gate, as an optical coupler and secondary shunt regulator are used. 2 FB The feedback pin should to be connected to the output of the error amplifier for achieving the voltage control loop. The FB should be connected to the output of the optical coupler if the error-amplifier is equipped at the secondary-side of the power converter. For the primary-side control application, FB is applied to connect a RC network to the ground for feedback-loop compensation. The input impedance of this pin is a 5 kΩ equivalent resistance. A 1/3 attenuator connected between the FB and the PWM circuit is used for the loop-gain attenuation. FAN6300A/H performs an open-loop protection once the FB voltage is higher than a threshold voltage (around 4.2 V) more than 55 ms. 3 CS Input to the comparator of the over-current protection. A resistor senses the switching current and the resulting voltage is applied to this pin for the cycle-by-cycle current limit. 4 GND The power ground and signal ground. A 0.1 µF decoupling capacitor placed between VDD and GND is recommended. 5 GATE Totem-pole output generates the PWM signal to drive the external power MOSFET.

Start Timer (VFB<VG) FAN6300A/H — Highly Integrated Quasi-Resonant Current Mode PWM Controller Typical Performance Characteristics (Continued) www.fairchildsemi.com 10 The FAN6300A/H PWM controller integrates designs to enhance the performance of flyback converters. An internal valley voltage detector ensures power system operates at Quasi-Resonant (QR) operation across a wide range of line voltage. The following descriptions highlight some of the features of the FAN6300A/H. Green-Mode Operation The proprietary green-mode function provides off-time modulation to linearly decrease the switching frequency under light-load conditions. VFB, which is derived from the voltage feedback loop, is taken as the reference. In Figure 19, once VFB is lower than VN, tOFF-MIN increases linearly with lower VFB. The valley voltage detection signal does not start until tOFF-MIN finishes. Therefore, the valley detect circuit is activated until tOFF-MIN finishes, which decreases the switching frequency and provides extended valley voltage switching. However, in very light load condition, it might fail to detect the valley voltage after the tOFF-MIN expires. Under this condition, an internal tTIME-OUT signal initiates a new cycle start after a 9 μs delay (with 5 µs delay for H version). Figure 20 and Figure 21 show the two different conditions. Startup Current For startup, the HV pin is connected to the line input or bulk capacitor through an external diode and resistor, RHV, which are recommended as 1N4007 and 100 kΩ. Typical startup current drawn from the HV pin is 1.2 mA and it charges the hold-up capacitor through the diode and resistor. When the VDD voltage level reaches VDD-ON, the startup current switches off. At this moment, the VDD capacitor only supplies the FAN6300A/H to maintain VDD until the auxiliary winding of the main transformer provides the operating current. tO F F -M I N 2 .1 m s Valley Detection The DET pin is connected to an auxiliary winding of the transformer via resistors of the divider to generate a valley signal once the secondary-side switching current discharges to zero. It detects the valley voltage of the switching waveform to achieve the valley voltage switching. This ensures QR operation, minimizes switching losses, and reduces EMI. Figure 17 shows divider resistors RDET and RA. RDET is recommended as 150 kΩ to 220 kΩ to achieve valley voltage switching. When VAUX (in Figure 17) is negative, the DET pin voltage is clamped to 0.3 V. 38/13 μ s 8 /3μ s 1 .2 V VFB 2 .1 V Figure 19. VFB vs. tOFF-MIN Curve Figure 17. Valley Detect Section The internal timer (minimum tOFF time) prevents gate retriggering within 8 µs (3 µs for H version) after the gate signal going-low transition. The minimum tOFF limit prevents system frequency being too high. Figure 18 shows a typical drain voltage waveform with first valley switching. Figure 20.

First Valley Switching © 2009 Fairchild Semiconductor Corporation FAN6300A / FAN6300H • Rev. 1.0.2 FAN6300A/H — Highly Integrated Quasi-Resonant Current Mode PWM Controller Operation Description www.fairchildsemi.com 11 VDD Over-Voltage Protection Peak-current-mode control is utilized to regulate output voltage and provide pulse-by-pulse current limiting. The switch current is detected by a sense resistor into the CS pin. The PWM duty cycle is determined by this currentsense signal and VFB. When the voltage on CS reaches around VLIMIT = (VFB-1.2)/3, the switch cycle is terminated immediately. VLIMIT is internally clamped to a variable voltage around 0.85 V for output power limit. VDD over-voltage protection prevents damage due to abnormal conditions. Once the VDD voltage is over the VDD over-voltage protection voltage (VDD-OVP) and lasts for tVDDOVP, the PWM pulse is disabled until the VDD voltage drops below the UVLO, then starts again. Output Over-Voltage Protection The output over-voltage protection works by the sampling voltage, as shown in Figure 23, after switch-off sequence. A 4 μs (1.5 μs for H version) blanking time ignores the leakage inductance ringing. A voltage comparator and a 2.5 V reference voltage develop an output OVP protection. The ratio of the divider determines the sampling voltage of the stop gate, as an optical coupler and secondary shunt regulator are used. If the DET pin OVP is triggered, the power system enters latch-mode until AC power is removed. Leading-Edge Blanking (LEB) Each time the power MOFFET switches on, a turn-on spike occurs on the sense resistor. To avoid premature termination of the switching pulse, lead-edge blanking time is built in. During the blanking period, the current limit comparator is disabled; it cannot switch off the gate driver. Under-Voltage Lockout (UVLO) The turn-on, PWM-off, and turn-off thresholds are fixed internally at 16/10/8 V. During startup, the startup capacitor must be charged to 16 V through the startup resistor to enable the IC. The hold-up capacitor continues to supply VDD until energy can be delivered from the auxiliary winding of the main transformer. VDD must not drop below 10 V during this startup process. This UVLO hysteresis window ensures that hold-up capacitor is adequate to supply VDD during startup. Gate Output The BiCMOS output stage is a fast totem-pole gate driver. Cross conduction has been avoided to minimize heat dissipation, increase efficiency, and enhance reliability. The output driver is clamped by an internal 18 V Zener diode to protect power MOSFET transistors against undesired over-voltage gate signals. Figure 23. Voltage Sampled After 4μs (1.5 μs for FAN6300H version) Blanking Time After Switch-Off Sequence Over-Power Compensation Short-Circuit and Open-Loop Protection To compensate this variation for wide AC input range, the DET pin produces an offset voltage to compensate the threshold voltage of the peak current limit to provide a constant-power limit. The offset is generated in accordance with the input voltage when PWM signal is enabled. This results in a lower current limit at high-line inputs than low-line inputs. At fixed-load condition, the CS limit is higher when the value of RDET is higher. RDET also affects the H/L line constant power limit. The FB voltage increases every time the output of the power supply is shorted or overloaded. If the FB voltage remains higher than a built-in threshold for longer than tDOLP, PWM output is turned off. As PWM output is turnedoff, the supply voltage VDD begins decreasing. FAN6300A/H — Highly Integrated Quasi-Resonant Current Mode PWM Controller Current Sensing and PWM Current Limiting When VDD goes below the PWM-off threshold of 10 V, VDD decreases to 8 V, then the controller is totally shut down. VDD is charged up to the turn-on threshold voltage of 16 V through the startup resistor until PWM output is restarted. This protection feature continues as long as the overloading condition persists. This prevents the power supply from overheating due to overloading. Figure 22.
