Maximum Output Current of TPS62050
PDF, 51 Kb, 档案已发布: Mar 19, 2003
The TPS62050 is a highly integrated synchronous step-down dc/dc converter capable of delivering output up to 800 mA. However, the maximum output current is limited by parameters such as ambient temperature, input-output voltage ratio, and switching frequency. This application report provides the maximum allowable output current of the TPS62050.

Adding Hysteresis to Low Battery Input on the TPS6205x (Rev. A)
PDF, 89 Kb, 修订版: A, 档案已发布: Nov 28, 2007
The low-battery input (LBI), available on several step-down converters, is often used to shut down the converter when the input voltage falls below a set threshold. This prevents damage to the battery and signals that the battery is at the end of its life and should be charged or replaced. Batteries have internal resistance that causes the voltage to drop as the load increases. This internal resis

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.
