Preliminary Specification Highly-Integrated Green-Mode PWM Controller www.DataSheet4U.com SG6842 zero-load conditions, the power supply enters burst-mode. This completely shuts off PWM output. Then, the output restarts just before the supply voltage, VDD, drops below the UVLO voltage. This green-mode function enables the power supply to easily meet international power conservation requirements. For improved power conversion efficiency, the SG6842 series is manufactured using the BiCMOS process. This allows the start-up current to be reduced to 20uA, and the operating current to be reduced to 4mA. For even higher power conversion efficiency, a large start-up resistance can be used. Built-in synchronized slope compensation ensures the stability of peak current mode control.
