Brief Introduction

 With advanced anti-overload and anti-saturation technology and being a switching power supply controller capable of satisfying higher standard for environment protection, TFC719 is applicable for mini-watt switching power supply devices such as cell-phone chargers.

Features

 Being designed with advanced anti-overload and anti-saturation technology, capable of timely preventing failures such as overload, saturation of the switching transformer, output short circuit and etc.;

 Using built-in power triode as the switching tube, and at the same time completing the start-up by using its amplifying capacity to reduce the power consumption of the start-up resistor more than ten times;

 With built-in slope compensation circuit, thermal protection circuit and slope current driving circuit;

 Broad voltage output power up to 5.5W and 220V AC output power up to 8W; standby power consumption below 0.25W.
