FA551x - CMOS IC

General 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.

Key Features

  • Low current 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.
  • 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-.

FA551X series FA5510P (N), FA5511P (N) FA5514P (N), FA5515P (N) ■ 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 highperformance and compact power supply can be created because not many external discrete components are needed.
