Bipolar IC

For Switching Power Supply Control

FA531X series

FA5310BP(S), FA5314P(S), FA5316P(S)

FA5311BP(S), FA5315P(S), FA5317P(S)

■ Dimensions, mm

Á SOP-8

■ 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)

0.6

0.4^±0.11.27^±0.2

• Output ON/OFF control function by external signal

• Overvoltage cutoff function in latch mode

• Undervoltage malfunction prevention function

• Low standby current (90µA typical)

Á DIP-8

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

• 8-pin package (DIP/SOP)

■ Applications

• Switching power supply for general equipment
