Description

FSCQ1565RTYDTU, A Quasi-Resonant Converter (QRC) typically shows lower EMI and higher power conversion efficiency compared to a conventional hard-switched converter with a fixed switching frequency. Therefore, a QRC is well suited for noise-sensitive applications, such as color TV and audio. Each product in the FSCQ seriescontains an integrated Pulse Width Modulation (PWM) controller and a SenseFET. This seriesis specifically designed for quasi-resonant off-line Switch Mode Power Supplies (SMPS) 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.

What’s more?

Compared with a discrete MOSFET and PWM controller solution, the FSCQ seriescan reduce total cost, component count, size, and weight;while increasing efficiency, productivity, and system reliability. These devices provide a basic platform for cost-effective designs of quasi-resonant switching flyback converters.Related ResourcesAN-4146 —Design Guidelines for Quasi-Resonant Converters Using FSCQ-Series Fairchild Power SwitchAN-4140 —Transformer Design Consideration for Offline Flyback Converters Using Fairchild PowerSwitchOrdering Information Part NumberPackageMarking CodeBVDSS(V)RDSONMax.
