Description
The FSD200 and FSD210 are integrated Pulse Width Modu-
lators (PWM) and Sense FETs specially designed for high
performance off-line Switch Mode Power Supplies (SMPS)
with minimal external components. Both devices are mono-
lithic high voltage power switching regulators which com-
bine an LDMOS Sense FET with a voltage mode PWM
control block. The integrated PWM controller features in-
clude: a fixed oscillator with frequency modulation for re-
duced EMI, Under Voltage Lock Out (UVLO) protection,
Leading Edge Blanking (LEB), optimized gate turn-on/turn-
off driver, thermal shut down protection (TSD), temperature
compensated precision current sources for loop compensa-
tion and fault protection circuitry. When compared to a dis-
crete MOSFET and controller or RCC switching converter
solution, the FSD200 and FSD210 reduce total component
count, design size, weight and at the same time increase effi-
ciency, productivity, and system reliability. The FSD200
eliminates the need for an auxiliary bias winding at a small
cost of increased supply power. Both devices are a basic plat-
form well suited for cost effective designs of flyback convert-
ers.
