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-

mized gate turn-on/turn-off driver, Thermal Shut Down

(TSD) protection, Abnormal Over Current Protection

(AOCP) and 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 FSDx321 reduce total

component count, design size, weight and at the same time

increase efficiency, productivity, and system reliability. Both

devices are a basic platform well suited for cost effective

designs of flyback converters.
