Description
The FSDx321(x stands for H, L) are integrated Pulse Width
Modulators (PWM) and Sense FETs specifically designed
for high performance offline Switch Mode Power Supplies
(SMPS) with minimal external components. Both devices
are integrated high voltage power switching regulators
which combine an avalanche rugged Sense FET with a cur-
rent mode PWM control block. The integrated PWM con-
troller features include: a fixed oscillator with frequency
modulation for reduced EMI, Under Voltage Lock Out
(UVLO) protection, Leading Edge Blanking (LEB), opti-
