ICE5QR4780BG-1 CoolSET™ 5th generation quasi-resonant flyback controller with integrated 800V CoolMOS™ SJ MOSFET in SMD package
综述
The Quasi resonant flyback controller with a valley-switching scheme and an 800V CoolMOS™ P7 superjunction MOSFET in single DSO-12 package offers a high level of integration that provides a comprehensive suite of protection features, frequency jittering to minimize EMI, and frequency reduction in tandem with the decrease of load to improve overall efficiency. On top, the active burst mode improves light-load/standby performance.
