g n i h tors c t i a Sw egul R STR-A6151 AND STR-A6159 Universal-Input/13 or 16 W Flyback Switching Regulators 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. Covering the power range from below 13 watts to 16 watts for a 230 VAC input, or 10 to 12 watts for a universal (85 to 264 VAC) input, these devices can be used in a range of applications, from DVD and VCR players to ac adapters for cellular phones and digital cameras.
