Summary
Primary-Side-Regulation PWM with POWER MOSFET Integrated
Description
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 FSEZ1317A 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.
