Shenzhen LIZE Electronic Technology Co., Ltd SPECIFICATION L2263 Current Mode PWM Controller VERSION 1.2 reserves the right to change this documentation without prior notice Shenzhen LIZE Electronic Technology Co., Ltd L2263 Current Mode PWM Controller Description L2263 is highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyblack converter applications in sub 60W 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. VDD low startup current and low operating current contribute to a reliable power on startup design with L2263.A large value resistor could thus be used in the startup circuit to minimize the standby power. L2263 offers complete protection coverage with automatic self- recovery feat...
