应用须知
- Using The TPS6235x Without The I2C InterfacePDF, 69 Kb, 档案已发布: May 17, 2007
The TPS6235x series of DC/DC converters have an I2C-compatible interface that facilitates changing the output voltage for dynamic voltage-scaling applications. However, it is possible to use the TPS6235x series of converters, without the I2C interface, as a standalone DC/DC converter that can be dynamically switched between two fixed voltages. This technique does not work for the TPS62351. - Powering OMAP3 With TPS6235x: Design-In GuidePDF, 296 Kb, 档案已发布: Dec 3, 2008
The OMAP35xx Applications Processors have a diverse set of power management features which potentially enable lower cost power solutions based on your application. This design-in guide describes a power solution based on the TPS6235x device. This guide can be used to evaluate this solution for your design or help you make decisions when designing in this solution. - Optimizing Transient Response of Internally Compensated DC-DC Converters (Rev.

- Performing Accurate PFM Mode Efficiency Measurements (Rev. A)PDF, 418 Kb, 修订版: A, 档案已发布: Dec 11, 2018
When performing measurements on DC-DC converters using pulse frequency modulation(PFM)or any power save mode proper care must be taken to ensure that the measurements are accurate. An accurate PFM mode efficiency measurement is critical for systems which require high efficiency at low loads such as in smart home systems tablets wearables and metering.
