LM26480
November 1, 2010
Externally Programmable Dual High-Current Step-Down
DC/DC and Dual Linear Regulators
General Description
The LM26480 is a multi-functional Power Management Unit,
optimized for low-power digital applications. This device inte-
grates two highly efficient 1.5A step-down DC/DC converters
and two 300 mA linear regulators. The LM26480 is offered in
a tiny 4 x 4 x 0.8mm LLP-24 pin package.
