BU33UV7NUX is a synchronous buck-boost convertor with low power consumption, which provides a power supply for products powered by either two-cell alkaline/ NiCd/ NiMH or one-cell Li-ion or Li-polymer battery.
<Key Features>
1. High efficiency with load current mode switching
A built in load current mode switching function makes it possible to achieve superior energy-saving performance for a wide range of dry-cell battery applications by performing switching at the mode terminal. In H Mode high efficiency is maintained in the high load current region, while L Mode improves efficiency at light loads.
2. Low current consumption + low voltage drive
The operating mode can be selected based on the application load current. Industry-leading current consumption is achieved in either mode (13uA in H Mode and only 7uA in L Mode). As a result when taking into account battery life, operation up to an extra 120 days is possible in H Mode and up to an extra 175 days in L Mode is achievable.
ROHM's new BU33UV7NUX boost DC/DC converter IC maintains stable, long-term output - even with a single dry-cell battery.
