Description
This highly integrated PWM controller provides several enhancements designed to meet the low standby-power
needs of low-power SMPS. To minimize standby power consumption, a proprietary green-mode function
provides off-time modulation to linearly decrease the switching frequency under light-load conditions. This
green-mode function enables the power supply to meet even strict power conservation requirements.
