1 Introduction

The TPS62122 is a high-efficiency, synchronous step-down, dc-dc converter optimized for low-power

applications. The wide operating input voltage range of 2 V to 15 V supports energy harvesting and

battery-powered as well 9-V or 12-V line-powered applications.

The TPS62122EVM-586 is a fully assembled and tested platform for evaluating the operation and

performance of the TPS62122 converter. The TPS62122EVM-586 has an input voltage range from 2.0 V

up to 15 V, and the output voltage is adjustable with an external feedback divider network in the range of

1.2 V to 5.5 V. The maximum output current of the EVM circuit is 75 mA.
