Datasheet Synchronous Boost DC/DC Converter
(LOAD:500mA@Vout=3.3V,Vin=1.8V)
BU33UV7NUX
General Description
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,
