Quasi Resonant CoolSET™ Power ICs

Infineon Quasi-Resonant CoolSET™ Power ICs are optimized for off-line switch power supplies in cascode configurations. These Infineon ICs are housed in single packages with two separate chips: one is a controller chip and the other is an HV MOSFET chip. The ICs can achieve lower EMI and higher efficiency with improved digital frequency reduction through the proprietary novel Quasi-Resonant operation. The enhanced Active Burst Mode enables flexibility in standby power range selection. The product has a wide operation range (10.0V to 25.5V) of IC power supply and lower power consumption.
