Application Notes
- Discrete Charge Pump Design (Rev. A)PDF, 190 Kb, Revision: A, File published: Jul 16, 2010
Many applications require an auxiliary power supply in addition to a primary power supply. For example, TFT-LCD applications can require +20 V to +30 V and +10 V to +20 V. As a result of cost, board space, or inventory, a separate converter may not be appropriate for some applications. This document demonstrates a simple charge pump circuit that provides the auxiliary positive voltage using the TP - Low Cost 1W Isolated Power Supply Solution with TPS61085PDF, 175 Kb, File published: Jun 26, 2012

- Performing Accurate PFM Mode Efficiency Measurements (Rev. A)PDF, 418 Kb, Revision: A, File published: 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.
