FLS6617
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 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.
