Datasheet Synchronous Boost DC/DC Converter (LOAD:500mA V =3.3V , V =1.8V) OUT IN BU33UV7NUX General Description Key Specifications BU33UV7NUX is a synchronous boost convertor with low Input Voltage Range 0.6V to 4.5V power consumption and provides a power supply for Fixed Output Voltage 3.3V products powered by either two-cell alkaline/NiCd/NiMH Efficiency 94%(Max) or one-cell alkaline/Li-ion or Li-polymer battery. Current Consumption 7A(MODE=Low) Output currents can go as high as 500mA(VIN=1.8V). 13A(MODE=High) BU33UV7NUX has reset circuit. (Detection voltage:1.5V, Release Voltage:1.9V) Start-up Voltage 0.9V BU33UV7NUX output voltage is fixed 3.3V by internal resistor divider. V is connected with V when V OUT IN IN Package W(Typ) x D(Typ) x H(Max) voltage is higher than 3.3V.
