Infineon REF_ICC80QSG_84W1_BPA Flyback Controller for REF_ICC80QSG_84W1_BPA for 700 V CoolMOS P7, Quasi Resonant

The REF_ICC80QSG_84W1_BPA is a flyback-based reference design, scalable from 65 W to >100 W and aimed for 12 V/18 V Li-Ion battery packs. It is based on the quasi-resonant flyback controller ICC80QSG and the renowned 700 V CoolMOS™ P7 technology in the small footprint and wave solderable SOT-223 package. The controller burst mode enables low standby <200 mW. The reference board includes a secondary-side auxiliary supply for battery switch and supply of a MCU. Measured efficiency is >90 percent at 230 VAC input voltage, providing excellent performance versus BOM cost ratio for chargers for consumer appliances.
