ICE2QR0665,Quasi-Resonant PWM Controller,DIP-8

The ICE2QR0665 is a high-performance quasi-resonant PWM controller with an integrated 650V CoolMOS®, designed for off-line switch-mode power supply (SMPS) applications. Its innovative quasi-resonant operation significantly reduces switching losses and enhances system efficiency while minimizing EMI, making it an excellent choice for LCD monitors, set-top boxes, DVD players, and other electronic devices.

Equipped with Active Burst Mode, the ICE2QR0665 ensures ultra-low standby power consumption (<100mW), complying with stringent energy efficiency standards. Digital frequency reduction further optimizes performance by reducing switching frequency as load decreases, ensuring stable and efficient operation under varying conditions.

The controller includes comprehensive protection features such as over-temperature, over-voltage, overload, and short-winding protection, providing reliable operation in demanding environments. With its compact DIP-8 package, the ICE2QR0665 simplifies assembly and integration into compact designs, making it a versatile solution for energy-efficient power supply designs.
