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.

Overview

Key Features

Internally synchronized PFC and PWM in one 8-pin IC.
Proprietary one-pin voltage error ampliﬁer with advanc input current shaping technique.
Peak or average current, continuous boost, leading edge PFC (Input Current Shaping Technology).
High efﬁciency trailing-edge current mode PWM.
Low supply currents; start-up: 150µA typ. , operating: 2mA typ.
Synchronized leading and trailing edge modulation.
Reduces ripple current in the storage.
