Overview
Product Specification High-integrated Green-mode PWM Controller SG6841 FEATURES Green-mode PWM to support “Blue Angel” Norm Low start up current 30uA Low operation current 3mA Leading-edge blanking Built-in synchronized slope compensation Constant output power limit for universal AC input Current mode operation Cycle-by-cycle current limiting Under voltage lockout (UVLO) Programmable PWM frequency GATE output maximum voltage clamped at 18V Totem pole output includes soft driving for better EMI Build-in limited-power-control to meet safety requirement Programmable over-temperature protection Few external components & low cost solution DESCRIPTION This highly integrated PWM controllers, SG6841 series, provides several features to enhance the performance of low power flyback converters.
To minimize standby power consumption, the proprietary green-mode function provides off-time modulation to linearly decrease the switching frequency under light-load conditions.
