s 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.
s 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 (90
A typical)
Exclusive choices by circuits (See selection guide on page 25)
8-pin package (DIP/SOP)
s Applications
Switching power supply for general equipment
Bipolar IC
For Switching Power Supply Control
