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
controller IC. PWM controller features integrated fixed oscil-
lator, under voltage lock out, leading edge blanking, opti-
mized gate turn-on/turn-off driver, thermal shut down
protection, over voltage protection, temperature compensated
precision current sources for loop compensation and fault
protection circuit. Compared to discrete MOSFET and con-
troller 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 effec-
tive design in either a flyback converter or a forward con-
verter.
