SGP400 controller equivalent, low-power green-mode pwm flyback power controller.
* Linearly decreasing PWM frequency
* Green-mode under light-load and zero-load
conditions
* Constant voltage (CV) and constant current (CC)
* No secondar.
Low-power flyback power converters, such as:
* Battery chargers for cellular phones, cordless phones,
PDAs, digital .
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 t.
