Description
Each product in the FSDx321 (x for H, L) family consists of
an integrated Pulse Width Modulator (PWM) and Sense
FET, and is specifically designed for high performance off-
line Switch Mode Power Supplies (SMPS) with minimal
external components. Both devices are integrated high volt-
age power switching regulators which combine an avalanche
rugged Sense FET with a current 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), an optimized gate turn-on/turn-off driver,
Thermal Shut Down (TSD) protection, Abnormal Over Cur-
rent Protection (AOCP) and temperature compensated preci-
sion current sources for loop compensation and fault
protection circuitry. When compared to a discrete MOSFET
and controller or RCC switching converter solution, the
FSDx321 devices reduce total component count, design size,
weight while increasing efficiency, productivity and system
reliability. Both devices provide a basic platform that is well
suited for the design of cost-effective flyback converters.
