SG6842 Highly Integrated Green-Mode PWM Controller

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..
