FA5511P Overview
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.
FA5511P 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-OFF function by external signal
- Latch-mode overvoltage shutdown function
- Undervoltage lockout function (16.5V ON / 9V OFF)
