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 oscillator,
under voltage lock out, leading edge blanking, optimized gate
turn-on/turn-off driver, thermal shut down protection, over volt-
age protection, and temperature compensated precision current
sources for loop compensation and fault protection circuitry.
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.
