FA5311BP - Fuji Electric

FA5311BP Bipolar IC For Switching Power Supply Control

The FA531X series are bipolar ICs for switching power supply control that can drive a power MOSFET. These ICs contain many functions 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. 1 6.05 4 +0.1 –0.05 • Drive circuit for connecting a power MOSFET.
