3 Description
The TPS65132 family is designed to supply
positive/negative driven applications. The device uses
a single inductor scheme for both outputs to provide
the user smallest solution size, a small bill-of-material
as well as high efficiency. The devices offer best line
and load regulation at low noise. 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 fixed 3.3-V and 5-V rails. The
TPS656132 family provides 80 mA and 150 mA
output current options with programmability to 40 mA.
There are both CSP and QFN package options
available.
