BU33DV5G
1.75V to 4.5V, 10mA 1ch Synchronous Boost DC/DC Converter
The BU33DV5G devices provide a power supply solution for products powered by either two-cell alkaline, NiCd or NiMH, or one-cell Li-ion or Li-polymer battery. Output currents can go as high as 10mA while using two alkaline, and discharge it down to 1.8 V. The boost converter is based on a fixed frequency, Pulse-width-modulation (PWM) controller using a synchronous rectifier to obtain maximum efficiency. The maximum peak current in the boost switch is typically limited to a value of 10 mA. BU33DV5G output voltage is fixed by an internal resistor divider. The device is packaged in a 5-pin small SSOP5 package.
