Fairchild Power Switch(SPS)

Features

Description

• Wide operatimg frequency range up to (150kHz)

• Pulse by pulse over current limiting

• Over load protection

• Over voltage protecton (Min. 23V)

• Internal thermal shutdown function

• Under voltage lockout

• Internal high voltage sense FET

• External sync terminal

• Latch up Mode

The SPS product family is specially designed for an offline

SMPS with minimal external components. The SPS consist

of high voltage power SenseFET and current mode PWM

Controller IC. control IC features a trimmed oscillator, under

voltage lock-out, leading edge blanking, optimized gate turn-

on/turn-off driver, thermal shut down protection, over volt-

age protection, temperature compensated precision current

sources for loop compensation and fault protection circuit.

Compared to discrete MOSFET and controller or RCC

switching converter solution, a SPS can reduce total compo-

nent count, design size, weight and at the same time increase

&efficiency, productivity, and system reliability. It has a

basic platform well suited for cost-effective Monitor power

supply.
