LM2735Y 5-Pin SOT23 Demo
Board
Introduction
The demo board included in this shipment converts 3V to 5.5V
input to 12V output for up to 500mA load current using the
LM2735Y 520kHz 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
