SPS KA2S0880
SPSThe SPS product family is specially designed for an off line
SMPS with minimal external component. The SPS consist of
high voltage Power SenseFET and current mode PWM IC.
Included control IC features a tr-immed 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
source 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 monitor power
supply.
FEATURES Wide operating frequency range up to 150kHz Pulse by pulse over current limiting Over load protection Over voltage protection (Min. 23V) Internal thermal shutdown function Under voltage lockout Internal high voltage sense FET External sync terminal Latch up Mode
