This highly integrated PWM controller provides several special enhancements designed to meet the low standby power needs of low-power SMPS. The proprietary green-mode function provides off-time modulation to linearly decrease the switching frequency under light-load conditions to minimise standby power consumption. This green-mode function enables the power supply to meet even the strictest power conservation…
