SPS
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 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.
