Fairchild Power Switch(SPS)
www.fairchildsemi.com
Features
• Wide operating frequency range up to 150KHz
• Pulse by pulse over current limiting
• Over load protection
• Over voltage protection (Min. 23V)
• Internal thermal shutdown function
• Under voltage lockout
• Internal high voltage sense FET
• External sync terminal
• Latch up Mode
Description
The SPS product family is specially designed for an off-line
SMPS with minimal external components. The SPS consist of
high voltage power SenseFET and current mode PWM Control-
ler IC. PWM controller features integrated fixed oscillator,
under voltage lockout, 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 switch-
ing converter solution, a SPS can reduce total component 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 design in monitor power supply.
