The Texas Instruments TPS65020EVM is an integrated Power Management IC for applications that are
powered with one Li-Ion or Li-Polymer cell, and require multiple power rails. The TPS65020 contains three
highly efficient switching step-down converters, two LDOs, and additional status and I/O pins. The device
is controlled via an I
2
C™ interface.
In order for this EVM to operate properly, the following components must be connected, and properly
configured.
A computer with a USB port is required to operate this EVM. The TPS65020 interface software, which is
run on the 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 TPS65020 internal registers through the USB port.
