SGP100 − Primary-side-control PWM controller

Obsolete as of 20-Jun-2012

This highly integrated PWM controller provides several features to enhance the performance of low-power flyback converters. The proprietary topology of SGP100 enables simplified circuit design for battery charger applications. The result is a low-cost, smaller and lighter charger than a conventional design or a linear transformer. 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 allows the power supply to meet power conservation requirements. The start-up current is only 10µA, which allows large start-up resistance for further power saving. A charger can be implemented with few external components and minimal cost. A typical output CV/CC characteristic envelope is provided.
