LM26480 Overview
The LM26480 is a multi-function, programmable Power Management Unit, optimized for low-power digital
applications. This device integrates two highly efficient 1.5A step-down DC/DC converters and two 300
mA Linear Regulators. The LM26480 is offered in a tiny 4 × 4 × 0.8 mm WQFN 24-pin package.

Evaluation Kit Overview
The LM26480 Evaluation kit comes preassembled with VOUT Buck1 set to 1.8V, VOUT Buck2 set to
3.3V, VOUT LDO1 set to 1.0V, and VOUT LDO2 set to 1.2V. These may not be what the user would like
for their evaluation, so it is possible to change any of the regulator outputs by adjusting its feedback
network. Details are in this document.
