BU33DV5G
BU33DV5G is Synchronous Boost DC/DC Converter manufactured by ROHM.
Description
The BU33DV5G devices provide a power supply solution for products powered by either two-cell alkaline, Ni Cd or Ni MH, or one-cell Li-ion or Li-polymer battery.
Output currents can go as high as 10m A 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 m A.
BU33DV5G output voltage is fixed by an internal resistor divider.
The device is packaged in a 5-pin small SSOP5 package.
