1Introduction

The TPS62065-67EVM-347 is a fully assembled and tested pair of PCBs for evaluating the TPS62065 and TPS62067 2-A step-down converters. The EVM comes configured with both a TPS62065 IC and a TPS62067 IC; there are two PCBs, one for each respective step-down converter IC.

1.1Features

•Input voltage range: 3.0 V to 6.0 V

•Adjustable output voltage: 0.8 V to VIN

•Up to 2.0-A output current

•3-MHz switching frequency

•Power Good output (TPS62067EVM only)

•Clock dithering

1.2TPS62065/67 Applications

The TPS62065 and TPS62067 step-down converters are ideal for these applications:

•POL

•Digital cameras

•PDAs, pocket PCs

•Portable media players

•DSP supply
