SPS
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 IC.
Included 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
voltage protection, and temperature compensated precision
current sources for loop compensation and fault protection
circuitry. Compared to discrete MOSFET and controller or
RCC switching 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.
