This product has Green Mode Fairchild Power Switch functions.
This is one of Power Switch Transistor. This part name is CQ1265RT.
The package is TO-220F-5L.
Manufacturers of the product is Fairchild, ON semicondcutor.
A Quasi-Resonant Converter (QRC) typically 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 quasiresonant off-line Switch Mode Power Supplies (SMPS) with minimal external components.
