STBB2 Description
The STBB2 is a fixed frequency, high efficiency, buck-boost DC-DC converter which provides output voltages from 1.2 V to 4.5 V starting from input voltage from 2.4 V to 5.5 V. The device can operate with input voltages higher than, equal to, or lower than the output voltage making the product suitable for single Li-Ion, multi-cell alkaline or NiMH applications where the output voltage is within the battery voltage...
