SC2569 Overview
SC2569 bines a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective off line flyback converter applications. PWM switching frequency at normal operation is externally programmable and trimmed to tight range. At no load or light load condition, the IC operates is extended ‘burst mode’ to minimize switching loss.
