FA5510P

Switching Power Supply Controller 8Pin DIP

■Description

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 high performance and compact power supply can be created because not many external discrete components are needed.
