Application Notes
- Calculating Output Capacitance to Meet Transient and Ripple RequirementsPDF, 189 Kb, File published: 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, File published: 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 - SMT Guidelines for Stacked Inductor (Inductor On Top) on Voltage Regulator ICPDF, 409 Kb, File published: Feb 22, 2016
