Datasheet

1.8V to 5.5V, 300mA 1ch

Synchronous Boost DC/DC Converter

BU33DV7NUX

●General Description

The BU33DV7NUX 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 300mA 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.

＜Available Features with MODE=0V＞

・Pass-Through Function2 during EN-OFF

・Disconnect Function during UVLO

・UVLO-detect Voltage:1.8V(typ)

・UVLO-release Voltage:2.0V(typ)

・PWM(Switching Frequency 600kHz)

＜Available Features with MODE=VIN＞

・Disconnect Function during EN-OFF and UVLO

・UVLO-detect Voltage:1.8V(typ)

・UVLO-release Voltage:2.0V(typ)

・PFM/PWM(Switching Frequency to 600kHz)

●Applications

BU33DV7NUX output voltage is fixed by an internal

resistor divider. When VIN voltage is higher than 3.3 V,

Vout is connected with Vin.
