Overview
g n i h tors c t i a Sw egul R STR-A6251 AND STR-A6252 Universal-Input/15 W 50 kHz Flyback Switching Regulators The STR-A6251 and STR-A6252 are 50 kHz PWM topology (with ±5% frequency jittering for minimum EMI) 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-A6252 features higher allowable switching current and lower on-resistance.
The STR-A6251 is also available for 67 kHz operation.
Covering the power range from below 21 watts or 24 watts for a 230 VAC input, or to 15 or 20 watts for a universal (85 to 264 VAC) inpu...
