By ROHM Semiconductor 60
ROHM Semiconductor's BU33UV7NUX is a synchronous buck-boost converter with low power consumption. It 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 500 mA while using two alkaline, and discharge it down to 1.8 V.
The BU33UV7NUX has a reset circuit (detection voltage: 1.5 V, reset voltage: 1.9 V) and an output voltage is fixed 3.3 V by internal resistor divider. VOUT is connected with VIN when VIN voltage is higher than 3.3 V.
