Application Notes
- Basic Calculation of an Inverting Buck-Boost Power Stage (Rev. A)PDF, 431 Kb, Revision: A, File published: Aug 28, 2017
This application note provides basic formulas that you need to design the power stage of an invertingbuck-boost converter. The premise is that the power switch is integrated in the IC and the rectification isdone by a diode (non-synchronous power stage). It provides all the formulas and considerations that youneed to select the external power components such as the inductor the diode and t - Understanding Undervoltage Lockout in Power Devices (Rev. A)PDF, 90 Kb, Revision: A, File published: Sep 19, 2018
Many integrated circuits include an undervoltage lockout (UVLO) function to disable the device at low supply voltages. Below the minimum supply voltage the function and performance of a device may be undefined making it impossible to predict system behavior. This application note explains how to correctly understand the undervoltage lockout specification in the data sheets of TI's power products. - Minimizing Ringing at the Switch Node of a Boost ConverterPDF, 201 Kb, File published: Sep 15, 2006
The application report explains how to use proper board layout and/or a snubber to reduce high-frequency ringing at the switch node of a boost converter. - Basic Calculation of a Boost Converter's Power Stage (Rev. C)PDF, 186 Kb, Revision: C, File published: Jan 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. - Basic Calculation of a Buck Converter's Power Stage (Rev. B)PDF, 202 Kb, Revision: B, File published: Aug 17, 2015
