PRODUCTION DATA.
NOTE
Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality.
The TPS65186 is used to power display screens in E-book applications, specifically E-Ink Vizplex display, by connecting the screen to the positive and negative charge pump, LDOs 1 and 2, and VCOM rails. The display screens size that can be supported up to 9.7 inches.
For this design example, use the parameters listed in Table 2 as the input parameters.
