CoolSET™ Switch Portfolio: Quasi-Resonant and Fixed Frequency

CoolSET™ Switch comes in two switching schemes. Fixed frequency (FF) suits designs that need predictable, easy-to-filter switching. Quasi-resonant (QR) minimizes switching losses and improves EMI for higher efficiency, especially at light load. FF scales up to 950 V avalanche-rugged CoolMOS™ P7. QR pairs an 800 V CoolMOS™ P7 in a single compact package with cascode start-up. Both integrate the controller and HV switch to reduce BOM count and board space.

High performance with the rugged CoolMOS™ technology

CoolSET™ Switch family offers the option of integrated 700 V, 800 V, and 950 V avalanche-rugged CoolMOS™ P7 Power MOSFETs - available in both through-hole and SMD. Superjunction technology eliminates the need for a heatsink, shrinks the footprint, and reduces BOM count with less board space, fewer components, and better thermal performance.
