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
IC. Included PWM controller features integrated fixed fre-
quency oscillator, under voltage lock-out, leading edge
blanking, optimized gate turn-on/turn-off driver, thermal
shutdown protection, over voltage protection, and tempera-
ture compensated precision current sources for loopcompen-
sation and fault protection circuitry. Compared to discrete
MOSFET and PWM controller or RCC solution, a SPS can
reduce total component count, design size, weight and at the
same time increase efficiency, productivity, and system reli-
ability. It has a basic platform well suited for cost-effective
design in either a flyback converter or a forward converter.
