Demo Board
Introduction
The demo board included in this shipment converts 3V to 5.5V
input to 3.3V output for up to 500mA load current using the
LM2735X 1.6MHz DC-DC switching converter. This is a 2-
layer board using the bottom layer as a ground plane.
A bill of materials below describes the parts used on this demo
board. A schematic and layout have also been included below
along with measured performance characteristics. The above
