BLOCK DIAGRAM

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 frequency

oscillator, under voltage lock-out, leading edge blanking, optimized

gate turn-on/turn-off driver, thermal shutdown protection, over

voltage protection, and temperature compensated precision current

sources for loop compensation 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 reliability.

It has a basic platform well suited for cost-effective design in either a

flyback converter or a forward converter.
