8A/800V QRC Power Switch
Features Wide operating frequency range up to 150KHz Pulse by pulse over current limiting Over current protection Over voltage protection (Min. 23V) Internal thermal shutdown function Under voltage lockout Internal high voltage sense FET External sync terminal Auto Restart 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 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 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 C-TV power supply.
