描述 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 26W SMPS design. This derivative has a lower UVLO voltage (9.85V) so that it can easier be used to optimize system 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.
