Notas de aplicación

  • Discrete Charge Pump Design (Rev. A)
    PDF, 190 Kb, Revisión: A, Archivo publicado: 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

  • Basic Calculation of a Boost Converter's Power Stage (Rev. C)
    PDF, 186 Kb, Revisión: C, Archivo publicado: enero 8, 2014
    This application note gives the equations to calculate the power stage of a boost converter built with an IC with integrated switch and operating in continuous conduction mode. It is not intended to give details on the functionality of a boost converter (see Reference 1) or how to compensate a converter. See the references at the end of this document if more detail is needed.

    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.
