CMOS IC

For Switching Power Supply Control

FA551X series

FA551X

FA5510P (N), FA5511P (N)

FA5514P (N), FA5515P (N)

■ Dimensions, mm

ꢀ SOP-8

■ Description

The FA551X series are the PWM type switching power supply

control ICs that can directly drive power MOSFET. These ICs

use a CMOS device with high dielectric strength (30V) to

implement low power consumption. These ICs contain many

function 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

• Low current consumption by CMOS process with high

dielectric strength (30V)

0.4^±0.11.27

• Standby current of 2µA or less (at Vcc=14V), and operating

current of 1.5mA (typ)

• Overvoltage protection function detecting the Vcc voltage

• A drive circuit for connecting a power MOSFET directly

• Output peak current: ±1.5A

ꢀ DIP-8

• Pulse-by-pulse overcurrent limiting function

• Overload protection function (latch or non-latch mode selectable)

• Output ON-OFF function by external signal

• Latch-mode overvoltage shutdown function

• Undervoltage lockout function (16.5V ON / 9V OFF)

• Reference voltage output (5V)
