3 Description
The TPS65132 is designed to support general
positive/negative driven applications. The device uses
a single inductor scheme in order to provide the user
the smallest solution size possible as well as high
efficiency. With its input voltage range of 2.5 V to
5.5 V, it is optimized for products powered by single-
cell batteries (Li-Ion, Ni-Li, Li-Polymer) and output
currents up to 80 mA. The device is delivered in a
WCSP package of 15 balls or in a QFN package of
20 pins.
Positive Output Voltage Range :
4 V to 6 V (0.1-V step)
