Overview

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.

Key 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 over a universal AC input range Current mode operation Cycle-by-cycle current limiting Under Voltage Lockout (UVLO) Programmable PWM frequency GATE output maximum voltage clamped at 18V VDD Over Voltage.
