Allegro MicroSystems STR-A6151

The STR-A6151 and STR-A6159 are PRC topology (fixed off-time) regulators specifically designed to satisfy the requirements for increased integration and reliability in flyback converters. They incorporate a primary control and drive circuit with avalanche-rated power MOSFETs. The STR-A6151 features higher switching current and avalanche-energy ratings and lower on-resistance.
