PSR Flyback PWM Controller with MOSFET Integrated for LED Lighting

General 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 FSEZ1317 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.

To minimize standby power consumption, the proprietary green mode provides off-time modulation to linearly decrease PWM frequency under light-load conditions. Green mode assists the power supply in meeting power conservation requirements.

By using the FSEZ1317, a charger can be implemented with few external components and minimized cost.
