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
