L2273, Current Mode PWM Controller

Shenzhen LIZE Electronic Technology Co., Ltd Current Mode PWM Controller L2273 SPECIFICATION L2273 Current Mode PWM Controller VERSION 1.0 reserves th.
L2273 is highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyblack converte.

Applications

* in sub 60W range. Fixed 65kHz PWM switching frequency at normal operation . 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
