■ 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)
Standby current of 2A 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
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)
