SG5701 - Low Cost Green-Mode PWM Controller
This highly-integrated PWM controller provides several special enhancements designed to meet the low standby-power needs of low-power SMPS.
To minimize standby power consumption, the proprietary green-mode function provides off-time modulation to linearly decrease the switching frequency under light
