● High efficiency trailing-edge current mode PWM
● Low supply currents; start-up: 150uA typ., operating: 2mA typ.
● Synchronized leading and trailing edge modulation
● Reduces ripple current in the storage capacitor between the PFC and PWM sections
● Over voltage, UVLO, and brownout protection
● PFC VCCOVP with PFC Soft Start
General Description
The FAN4803 is a space-saving controller for power factor corrected, switched mode power supplies that offers very low start-up and operating currents.
Power Factor Correction (PFC) offers the use of smaller, lower cost bulk capacitors, reduces power line loading and stress on the switching FETs, and results in a power supply fully compliant to IEC1000-3-2 specifications. The FAN4803 includes circuits for the implementation of a leading edge, average current “boost” type PFC and a trailing edge, PWM.
The FAN4803-1 's PFC and PWM operate at the same frequency, 67kHz. The PFC frequency of the FAN4803-2 is automatically set at half that of the 134kHz PWM. This higher frequency allows the user to design with smaller PWM components while maintaining the optimum operating frequency for the PFC.An over voltage comparator shuts down the PFC section in the event of a sudden decrease in load.The PFC section also includes peak current limiting for enhanced system reliability.

The goods are received on time, until I checked, as I will check the feedback. The seller sent on time, everything came safe and sound.
