The LM26480 is a multi-functional Power Management Unit, optimized for low-power digital applications. This device integrates two highly efficient 1.5A step-down DC/DC converters and two 300mA linear regulators. The LM26480 is offered in a tiny 4 x 4 x 0.8mm LLP-24 pin package.
The LM26480 Evaluation Kit requires the assembly of the user-specified feedback network. Pads are provided on the board to solder down surface mount resistors and capacitors. The LM26480 Evaluation Kit allows the user to effectively utilize all of the functions of the LM26480.
