FA551X series
CMOS IC
For Switching Power SupplyFCAo5n5tr1oXl
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 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 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)
