UC3869H Overview
The UTC UC3869H is a highly integrated current mode PWM control IC with high voltage start up, optimized for high performance, low standby power consumption and cost effective offline flyback converter applications. PWM switching frequency at normal operation is internally fixed and is trimmed to a tight range. At no load condition, the IC operates in power-saving mode for lower standby power, decreasing frequency...
