SGP400
Overview
This highly integrated PWM controller provides several features to enhance the performance of low-power flyback converters. To minimize standby power consumption, the proprietary green-mode function provides off-time modulation to linearly decrease the switching frequency under light-load and zero-load conditions.
- Linearly decreasing PWM frequency
- Green-mode under light-load and zero-load conditions
- Constant voltage (CV) and constant current (CC)
- No secondary feedback
- Low start-up current (8µA)
- Low operating current (3.6mA)
- Leading-edge blanking
- Constant power limit
- Universal AC input range
- Synchronized slope compensation
