Overview
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) 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 devices reduce total component count, design s...
