Synchronous Boost DC/DC Converter_BU33UV7NUX

BU33UV7NUX is a synchronous buck-boost convertor with low power consumption and provides a power supply for products powered by either two-cell alkaline/ NiCd/ NiMH or one-cell Li-ion or Li-polymer battery. Output currents can go as high as 500mA while using two alkaline, and discharge it down to 1.8 V. BU33UV7NUX has reset circuit. (Detection voltage:1.5 V, Release Voltage:1.9 V) BU33UV7NUX output voltage is fixed 3.3V by internal resistor divider. Vout is connected with Vin when VIN voltage is higher than 3.3 V.
