Introduction
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.

Setup This chapter describes the jumpers and connectors on the EVM, as well as how to properly connect, setup, and use the TPS65053EVM-389. Input/Output Connector Descriptions J1 - VLDO1 This header is the positive output of LDO1 linear regulator. This output is externally adjustable for the TPS65053 and is programmed to a value of 1.8 V on the EVM. - Page 3 Placing a shorting bar between EN LDO3 and ON ties the EN pin of LDO3 to VIN, thereby enabling LDO3. Placing a shorting bar between EN LDO3 and OFF ties the EN pin of LDO3 to GND, thereby disabling LDO3. SLVU262 – February 2009 TPS65053EVM-389 Submit Documentation Feedback...
