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.
