Chapter 1 Introduction The Texas Instruments TPS65011EVM-049 is an integrated power and battery management integrated circuit for applications that are powered with one Li-Ion or Li-Polymer cell and require multiple power rails. The TPS65011 contains two highly efficient switching step-down converters, two LDOs, a battery charger, and additional status and I/O pins. You control the device via an I2C interface. Topic 1.
Introduction 1.1 Requirements To operate this EVM properly, you must connect and properly configure the following components: ❏ Personal computer A computer with a USB port is required to operate this EVM. The TPS65011 interface software runs on the PC and communicates with the EVM via the PC USB port. You can send commands to the EVM and read the contents of the TPS65011 internal registers through the USB port.
Introduction Please see the application report Understanding the TPS65010 Software (SLVA154) for a detailed description of the software and how it works. When installing from a CD: 1) Insert the CD, it should start up automatically. If not, run the Start.bat file on the CD. 2) Install the TPS65010EVM controller program from the main menu first. 3) Install the USB drivers next. (Be sure the EV2300 board is not connected to your computer).

Chapter 2 Setup This chapter describes the jumpers and connectors on the EVM and how to properly connect, set up, and use the TPS65011EVM-049. Topic Page 2.1 Input/Output Connectors 2-2 2.
Setup 2.1 Input/Output Connectors Table 2-1 lists the input/output connectors Table 2-1. Input/Output Connectors Setup Connection Description J1-USB USB charger input/output header can be used as either an input or an output. If R6 is opened, then J1 can be used as an input. An external 5 V can be supplied to the EVM to simulate the USB 5-V bus. If R6 is shorted, J1 may be used as an output. The USB 5-V bus from the PC gets routed through the EV2300 to J5. Shorting R6 connects the USB 5-V bus to J1.
Setup Setup Connection Description J17-LDO1 Input/output connection for LDO1. VINLDO1 can be connected to an external supply or connected to another output voltage on the EVM. The EVM default configuration connects VMAIN to VINLDO1. Remove R25 if a voltage other than VMAIN is used as input to VINLDO1. J18-GND Return connection for LDO1 and LDO2 low dropout linear regulators J19-LDO2 Input/output connection for LDO2.
Setup 2-4 5) Connect the USB cable between the computer and the EVM. 6) Turn on all supplies and loads. 7) Run the TPS65010EVM software.
Chapter 3 Board Layout This chapter provides the TPS65011EVM-049 board layout and illustrations. Topic 3.
Board Layout 3.1 Layout Board layout is critical for all switch mode power supplies. Figures 1-5 show the board layout for the TPS65011EVM-049 PWB. 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 datasheet for specific layout guidelines. Figure 3-1.
