FA551x Datasheet (ETC)

FA551x, CMOS IC

The FA551X series are the PWM type switching power supply control ICs that can directly drive power MOSFET.

These ICs use a CMOS device with high dielectric strength (30V) to implement low power consumption.

These ICs contain many function in a small 8-pin package.

With these ICs, a highperformance
