Introduction
This EVM uses a TPS65132L to generate the positive and negative supply voltages needed by LCD
panels in smartphones and tablet PCs. It can also be used as a general-purpose power supply in
applications that need positive and negative supply rails (for example, op-amp or data acquisition circuits).
For easy performance evaluation of the TPS65132L, this EVM has:
•
Software with a Graphical User Interface (GUI) for reading, writing, exporting, and importing the device
configuration
•
A USB2ANY interface adapter to control the I
2
C bus
•
Test points for measuring the most important voltages
•
Jumpers for enabling and disabling the outputs
•
Input and output voltage sense terminals for making accurate four-terminal voltage measurements
