FA5304S数据手册FUJI中文资料规格书

描述 Description

The FA5304AP(S) and FA5305AP(S) are bipolar ICs for switching power supply control and can directly drive a power MOSFET. These ICs contain many functions in a small 8-pin package. With these ICs, a high-performance power supply can be created compactly because not many external components are needed.
