Infineon Technologies ICE2QR1065Z

Description

The CoolSET®-Q1 series (ICE2QRxx65Z) is the first generation of quasi-resonant integrated power ICs. It is optimized for off-line switch mode power supply applications such as LCD monitor, DVD R/W, DVDCombo, Blue-ray DVD, set top box, etc. Operating the MOSFET switch in quasi-resonant mode, lower EMI,higher efficiency and lower voltage stress on secondary diodes are expected for the SMPS. Based on theBiCMOS technology, the CoolSET®-Q1 series has a wide operation range (up to 25V) of IC power supply and lower power consumption. It also offers many advantages such as quasi-resonant operation till very low load which increases the average system efficiency,Active Burst Mode operation which enables an ultra-low power consumption at standby mode with small and controllable output voltage ripple, etc.
