BU33DV7NUX
BU33DV7NUX is Synchronous Boost DC/DC Converter manufactured by ROHM.
Description
The BU33DV7NUX 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 300m A while using two alkaline, and discharge it down to 1.8 V.
With the MODE pin, the BU33DV7NUX provides mode selection of PWM control or PFM/PWM automatic switching control. When load current is large, the product switches automatically to the PWM mode so that high efficiency is achievable over a wide range of load conditions. The maximum peak current in the boost switch is typically limited to a value of 1.85A.
BU33DV7NUX output voltage is fixed by an internal resistor divider. When VIN voltage is higher than 3.3 V,
Vout is connected with Vin.
