n 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.
n 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)
n Applications
• Switching power supply for general equipment
