FSEZ1317WA:Primary-Side-Regulation PWM with POWER MOSFET Integrated

FSEZ1317WA This third-generation Primary Side Regulation (PSR) and highly integrated PWM controller provides several features to enhance the performance of low-power flyback converters. The proprietary topology, TRUECURRENT®, of FSEZ1317WA enables precise CC regulation and simplified circuit design for battery-charger applications. A low-cost, smaller, and lighter charger results, as compared to a conventional design or a linear transformer.
