Introduction
The Texas Instruments TPS65023B/TPS650231EVM is an integrated power management integrated
circuit (IC) for applications that are powered with one Li-ion or Li-polymer cell and require multiple power
rails. The TPS65023B/TPS650231 contains three highly efficient switching step-down converters, two
LDOs, and additional status and I/O pins. The device is controlled via an I
1.1
Requirements
In order for this EVM to operate properly, the following components must be connected and properly
configured.
1.1.1
Personal 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.

Page 3: Input/Output Connector Description
Input/Output Connector Description This section describes the jumpers and connectors on the EVM, as well as how to properly connect, set up, and use the TPS65023B/TPS650231EVM-664. J1 – VIN Input voltage from external power supply, recommended maximum 5.5 V. Input current depends on load but typically is less than 2 A. - Page 4 Setup The following steps must be followed before the EVM can be operated. 1. Install the TPS65023B/TPS650231EVM software. 2. Connect input voltages and loads to the EVM. 3. Configure all EVM jumpers to factory setting.
- Page 5 Setting the Output Voltage for DCDC2, TPS650231 The TPS650231 does not feature these default output voltages. The output voltages of DCDC2 is externally adjustable only. The default configuration of the TPS650231EVM-664 is that R3 and R6 are not assembled. JP2 is not assembled.

Page 6: Board Layout
Layout Board layout is critical for all switch mode power supplies. layout for the TPS65023B/TPS650231EVM-664 PCB. The nodes with high switching frequencies and currents are short and are isolated from the noise-sensitive feedback circuitry. Careful attention has been given to the routing of high-frequency current loops. See the data sheet for specific layout guidelines. -
