Green Mode Power Switch
FSDH321, FSDL321
Description Each product in the FSDx321 (x for H, L) family consists of an
integrated Pulse Width Modulator (PWM) and SENSEFET, and is 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 SENSEFET® 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) prote...
