Adding Hysteresis to Low-Battery Input on the TPS6211x
PDF, 88 Kb, 档案已发布: Nov 2, 2009
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 must be charged or replaced. Batteries have internal resistance that causes the voltage to drop as the load increases. This internal resista

TPS6211X Driving EN and SYNC pin
PDF, 70 Kb, 档案已发布: Jan 15, 2008
The TPS6211x high-input-voltage buck converters operate over a wide, input-voltage range. The control and input signal can also be controlled from 1.8-V logic levels up to maximum input voltage.One characteristic of the EN and SYNC control circuits is the increase in leakage current when these pins are driven by a voltage level less than 4 V.In this application report, the difference in th

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.
