The FSD200 and FSD210 are integrated Pulse Width Modulators
(PWM) and Sense FETs specially designed for high
performance off-line Switch Mode Power Supplies (SMPS)
with minimal external components. Both devices are monolithic
high voltage power switching regulators which combine
an LDMOS Sense FET with a voltage mode PWM
control block. The integrated PWM controller features include:
a fixed oscillator with frequency modulation for reduced
EMI, Under Voltage Lock Out (UVLO) protection,
Leading Edge Blanking (LEB), optimized gate turn-on/turnoff
driver, thermal shut down protection (TSD), temperature
compensated precision current sources for loop compensation
and fault protection circuitry. When compared to a discrete
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 efficiency,
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 platform
well suited for cost effective designs of flyback converters.
