FA551X series
CMOS IC For Switching Power Supply Control
 
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.
 
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)
• Reference voltage output (5V)
• 8-pin package (DIP/SOP)
 
Absolute maximum ratings

Note: There are cases where the IC cannot output the rating current depending on Vcc voltage or temperature.
