1Introduction

The Texas Instruments TPS65023B/TPS650231EVM is an integrated power management integrated circuit (IC) for applications that are powered with one Li-ionorLi-polymercell and require multiple power rails. The TPS65023B/TPS650231 contains three highly efficient switchingstep-downconverters, two LDOs, and additional status and I/O pins. The device is controlled via an I2C interface (HPA172).

1.1Requirements

In order for this EVM to operate properly, the following components must be connected and properly configured.

1.1.1Personal Computer

A personal computer with a USB port is required to operate this EVM. The TPS65023B/TPS650231 interface software, which is run on the personal computer (PC), communicates with the EVM via the PC USB port. The user sends commands to the EVM as well as reads the contents of the TPS65023B/TPS650231 internal registers through the USB port.
