Green Mode Power Switch

for Valley Switching

Converter - Low EMI and

High Efficiency

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)

PDIP−8

CASE 626−05

PDIP8 GW

CASE 709AJ

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.

Compared with discrete MOSFET and PWM controller solutions,

the FSQ−series reduces total cost, component count, size and weight;

while simultaneously increasing efficiency, productivity, and system

reliability. This device provides a basic platform for cost−effective

designs of valley switching fly−back converters.
