XN1049 Datasheet (Innuovo) - Switch Power Supply PWM Controller

XN1049, Switch Power Supply PWM Controller

XN1049 which is optimized for high performance is a highly integrated current mode PWM control IC.

It is applied for switch power of the small-sized and medium-sized for example the power adaptor.

For lower the standby power and higher RoHS compliant, the IC has the Burst Mode function and very low

XN1049 Features

* Extended burst mode control for improving efficiency and minimum standby power Low startup current(4uA) Low operation current(1.4mA) Leading edge blan
