Shenzhen LIZE Electronic Technology Co., Ltd SPECIFICATION L2269 Current Mode PWM Controller VERSION 1.0 reserves the right to change this documentation without prior notice Shenzhen LIZE Electronic Technology Co., Ltd Description L2269 Current Mode PWM Controller Frequency Shuffling L2269 is highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyblack converter applications in sub 80W range. PWM switching frequency at normal operation is externally programmable to tight range. At no load or light load condition, the IC operates in extended ‘burst mode’ to minimize switching loss.Lower standby power and higher conversion efficiency in thus achieved.
