About This Manual This users guide describes the characteristics, operation, and use of the TPS65100EVM-030 evaluation module (EVM). This EVM contains Texas Instruments TPS65100 triple output LCD supply IC with linear regulator controller and VCOM buffer. This users guide includes EVM specifications, test results, schematic diagram, bill of materials (BOM), and recommended test setup.
Background 1.1 Background The TPS65100EVM uses a TPS65100 multichannel output IC to provide three LCD power rails, as well as a linear regulator controller to provide 3.3 V and a VCOM buffer. The goal of the EVM is to facilitate evaluation of the TPS65100.
Chapter 2 EVM Operation This chapter describes how to properly test the TPS65100 using the TPS65100EVM−030. Topic Page Input/Output Connect ......... Test Setup .
Input/Output Connect 2.1 Input/Output Connect The EVM connection points are described in the following paragraphs. 2.1.1 J1−VIN This is the positive connection to the input power supply. The leads to the input supply should be twisted and kept as short as possible. 2.1.2 J2−GND This is the return connection to the input power supply.
Test Setup 2.1.14 JP1 − Mode This is the charge pump mode pin connector. In order for the charge pump to operate as a voltage doubler, a jumper is installed to pull the mode pin to GND and C16 is left unpopulated. In order for the charge pump to operate as a voltage tripler, the jumper is removed and C16 is populated.

Layout 3.1 Layout Board layout is critical for all switch mode power supplies. Figures 3−1, 3−2, and 3−3 show the board layout for the HPA030 PWB. The switching nodes with high frequency noise are isolated from the noise sensitive feedback circuitry and careful attention has been given to the routing of high frequency current loops.
