XN1049 Switch Power Supply PWM Controller XN1049 Switch Power Supply PWM Controller General Description 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 startup current and working current. At the condition of no load or light load, the IC operates in extended ‘burst mode’ to minimize switching loss by lower the switching frequency. The low startup current and low operating current contribute to a reliable power on startup design with XN1049.
