FLS6617MX [Onsemi]

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 TRUECURRENT® technology of FLS6617 enables precise CC regulation and simplified circuit design for battery-charger applications leading to lower-cost, smaller, and lighter chargers, 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 FLS6617, a charger can be implemented with few external components and minimized cost.
