KA5H0265R
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.
