This highly integrated PWM controller provides several features to enhance the performance of low-power flyback converters. The proprietary topology of FSEZ1016A enables simplified circuit design especially for battery-charger applications. A low-cost, smaller, and lighter charger is the result when compared to a conventional design or a linear transformer. The startup current is only 10µA, which allows large startup resistance for further power saving.
To minimize the standby power consumption, the proprietary green-mode function provides off-time modulation to linearly decrease PWM frequency under light-load conditions. This green mode function assists the power supply in meeting power conservation requirements.
By using FSEZ1016A, a charger can be implemented with few external components and minimized cost. FSEZ1016A series controller is available in the 7-pin SOIC package.
