Product Summary
The str-A6252M is a 50 kHz PWM topology (with ±5% frequency jittering for minimum EMI) regulator specifically designed to satisfy the requirements for increased integration and reliability in flyback converters. The str-A6252M incorporates a primary control and drive circuit with avalanche-rated power MOSFETs. The str-A6252M features higher allowable switching current and lower on-resistance.
