  • Calculating Output Capacitance to Meet Transient and Ripple Requirements
    PDF, 189 Kb, Datei veröffentlicht: May 2, 2017
    This document provides guidance on how to calculate the amount of output capacitance needed to meet the transient and ripple requirements of a general buck converter design. DCAPx modulators are used in the example.
  • Accuracy-Enhanced Ramp-Generation Design for D-CAP3 Modulation (Rev. A)
    PDF, 493 Kb, Revision: A, Datei veröffentlicht: Apr 25, 2016
    D-CAP and D-CAP2 control schemes have been widely used in TI Switched-Mode DC-DC converters due to their fast transient response and no off-chip compensation. Offset generated by current sense ramp adds an error to VFB and Vout and hence reduces DC accuracy. This paper introduces a new D-CAP3 control scheme which greatly improves DC accuracy of the converter while maintaining the same fast transie
