FAN4803 Product details

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.

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.
