Want to post a buying lead? If you are not a member yet, please select the specific/related part number first and then fill the quantity and your contact details in the "Request for Quotation Form" on the left, and then click "Send RFQ".Your buying lead can then be posted, and the reliable suppliers will quote via our online message system or other channels soon.
A Valley Switching Converter generally shows lower EMIand higher power conversion efficiency than aconventional hard-switched converter with a fixedswitching frequency. The FSQ-series is an integratedPulse-Width Modulation (PWM) controller andSenseFET specifically designed for valley switchingoperation with minimal external components. The PWMcontroller includes an integrated fixed-frequencyoscillator, Under-Voltage Lockout, Leading EdgeBlanking (LEB), optimized gate driver, internal soft-start,temperature-compensated precise current sources forloop compensation, and self-protection circuitry.
Compared with discrete MOSFET and PWM controllersolutions, the FSQ-series reduces total cost, componentcount, size and weight; while simultaneously increasingefficiency, productivity, and system reliability. This deviceprovides a basic platform that is well suited for cost-effectivedesigns of valley switching fly-back converters.
