FSQ510MX Datasheet Green Mode Power Switch

Manufacturer: Fairchild (now onsemi)

General Description

A Valley Switching Converter ( VSC) generally s hows lower EMI and higher power conversion efficiency than a conventional hard-switched converter with a fixed switching frequency.

The FSQ510 is an i ntegrated Valley Switching Pulse Width Modulation (VS-PWM) controller and SenseFET specifically designed for offline Switch-Mode Power Supplies (SMPS) for valley switching with m inimal ex ternal c omponents.

T he VSPWM controller includes an integrated oscillator, undervoltage lockout (UVLO), leading-edge blanking (LEB), optimized gate dr iver, i nternal s oft-start, t emperaturecompensated precise c urrent s ources f or l oop compensation, and self-protection circuitry.
