ICE2QR2280Z1XKLA1

AC to DC Switching Converter Off-Line Switcher/SMPS Controller 52kHz Tube 7Pin PDIP

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.
