FSQ321 Datasheet Green Mode Power Switch

Manufacturer: onsemi

Overview: Green Mode Power Switch for Valley Switching Converter - Low EMI and High Efficiency FSQ0365, FSQ0265, FSQ0165,.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

A Valley Switching Converter generally shows lower EMI and higher power conversion efficiency than a conventional hard−switched converter with a fixed switching frequency.

The FSQ−series is an integrated Pulse−Width Modulation (PWM) controller and SENSEFET® specifically designed for valley switching operation with minimal external components.

The PWM controller includes an integrated fixed−frequency oscillator, under−voltage lockout, Leading−Edge Blanking (LEB), optimized gate driver, internal soft−start, temperature−compensated precise current sources for loop compensation, and self−protection circuitry.

Key Features
