Description
CQ1565RT is Green Mode Fairchild Power Switch (FPSTM). In general, a Quasi-Resonant Converter (QRC) shows lower EMI and higher power conversion efficiency compared to 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, and is specifically designed for quasi-resonant off-line Switch Mode Power Supplies (SMPS) with minimal external components.
The term “Green Mode Fairchild Power Switch” refers to a type of power switch integrated circuit (IC) developed by Fairchild Semiconductor (now part of ON Semiconductor). The Green Mode power switch ICs are designed for power supply applications that prioritize energy efficiency, low standby power consumption, and reduced environmental impact.
Fairchild Semiconductor (now ON Semiconductor) is a renowned semiconductor manufacturer that offers a range of power management ICs, including Green Mode power switches.
