FSCQ1265RT Overview
A Quasi-Resonant Converter (QRC) typically shows lower EMI and higher power conversion efficiency pared 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 series contains an integrated Pulse Width Modulation (PWM) controller and a SenseFET.
