EP68 3.3 V, 2 A DC-DC Power Supply

1 Introduction

This engineering report describes a 3.3 V / 2 A (6.6 W) DC-DC converter that is based on

a DPA423G device. This design is intended as an evaluation platform for DPA-Switch

devices in the low cost surface-mount DIP package. High operating efficiency, low parts

count, small footprint and low height make this an ideal choice for Power over Ethernet

(PoE) and VoIP DC-DC converter applications.

This report contains the power supply specification, schematic, bill of materials,

transformer documentation, printed circuit board layout, and performance data.
