■Description

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.

■Features

• Drive circuit for connecting a power MOSFET

• Wide operating frequency range (5 to 600kHz)

• Pulse-by-pulse overcurrent limiting function

• Overload cutoff function (Latch or non-protection mode selectable)

• Output ON/OFF control function by external signal

• Overvoltage cutoff function in latch mode

• Undervoltage malfunction prevention function

• Low standby current (90µA typical)

• Exclusive choices by circuits (See selection guide on page 25)

• 8-pin package (DIP/SOP)
