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 either a flyback converter or a
forward converter.
