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.
SG6842 Features
* Linearly decreasing PWM frequency Burst-mode at light load and zero load Low start-up current (20uA) Low operating current (4mA) Internal latch circuit for OTP, OVP Leading-edge blanking Built-in synchronized slope compensation Totem pole output with soft driving Improved EMI Constant power limit ov
