ICE2QR0680Z

离线SMPS集成了800V的CoolMOS准谐振PWM控制器？而在DIP7启动电池 Off-Line SMPS Quasi-Resonant PWM controller with integrated 800V CoolMOS? and startup cell in DIP7

Description:

Integrated power management IC with 800V avalanche rugged CoolMOS™, startup cell and QR current mode flyback PWM controller in DIP-7 package. Capable for 48W 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.
