The Texas Instruments TPS65053EVM-389 evaluation module (EVM) enables designers to evaluate the
operation and performance of the TPS65053 Power Management Integrate Circuit (PMIC) for applications
that require multiple power rails and are powered from a single Lithium Ion or Lithium Polymer cell. The
TPS65053 contains two efficient step-down switching converters, three low dropout (LDO) linear
regulators and a voltage monitor RESET output.

The TPS65053EVM-389 is setup according to the power requirements of the Freescale™ i.MX27
processor.
