Overview
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 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 current mode PWM control block.
