ICE2QR0665G

离线SMPS准谐振PWM控制器，集成650V的CoolMOS ？并在启动DSO-一十二分之十六细胞 Off-Line SMPS Quasi-Resonant PWM Controller with integrated 650V CoolMOS? and startup cell in DSO-16/12

Description:

Integrated power management IC with 650V avalanche rugged CoolMOS™, startup cell and QR current mode flyback PWM controller in DSO-16/12 packageCapable for 38W SMPS design. The quasi QR CoolSET™ series continues to deliver design agility and miniaturization. Upon the successful F3 CoolSET™, this new series offer the possibility of higher efficiency and better EMI performance. The digital frequency reduction feature score a very stable operation with decreasing load change, and the fold-back correction keep the maximum power limits within tolerance desired by SMPS designers. The active burst mode operation during low power consumption, remains market leaders in providing best-in-class power consumption during standby.
