DP2269 High Performance Current Mode PWM Controller GENERAL DESCRIPTION DP2269 is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter applications. PWM switching frequency at normal operation is internally fixed and is trimmed to tight range. At no load or light load condition, the IC operates in extended burst mode to minimize switching loss, which can achieve less than 75mW standby. VDD low startup current and low operating current contribute to a reliable power on startup and low standby design with DP2269.
