- 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 - Optimizing Resistor Dividers at a Comparator (Rev.

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.
