PT4201, Current-mode PWM Controller

PT4201 Current-mode PWM Controller GENERAL .
PT4201 is a highly integrated current mode PWM controller ， providing low standby power and cost effective system solution for the sub 30W flyback con.

Features

* power saving operation at no load or light load condition, PWM frequency is reduced to minimize switching loss and low standby power and high efficiency is thus achieved. PT4201 also features low VDD startup current which also contributes to low standby power. The built in LEB on the current sense i
