   产品概述 返回TOPpiW嘉泰姆

            The CXSU63033A is a synchronous, fixed frequency, step-up DC/DC converters delivering high efficiency in a 6 -lead ThinSOT package. Capable of supplying 5V at 800mA from a Lithium Battery input, the devices contain an internal NMOS switch and PMOS synchronous rectifier. 

         A switching frequency of 1.5MHz minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. The current mode PWM design is internally compensated, reducing external parts count. The CXSU63033A features automatic shifting to power saving PFM Mode operation at light loads. Antiringing control circuitry reduces EMI concerns by damping the inductor in discontinuous mode, and the devices feature low shutdown current of under 1μA. 

        Both devices are available in the low profile (1mm) SOT-23 package.
