■ 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

• Lowcurrent consumption by CMOS process with high dielectric strength (30V)

• Standby current of 2µA or less (at Vcc=14V), and operating current of 1.5mA (typ)

• Overvoltage protection function detecting the Vcc voltage

• Adrive circuit for connecting a power MOSFET directly

• Output peak current: ±1.5A

• 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)

• 8-pin package (DIP/SOP)
