The wide input voltage range SWIFTв„ў dc/dc converters are used typically as step-down converters where the derived output is a positive voltage less than the input voltage source. In some cases, it may be required to generate a negative voltage from the input voltage source. In such instances, it is possible to configure the TPS5430/20/10 devices in an inverting buck-boost topology, where the outpu - Using TPS5410/20/30/31/50 w/Aluminum/Ceramic Output Capacitors (Rev.

As internally compensated devices, the wide input step-down SWIFTв„ў DC/DC converters, including TPS5410/5420/5430/5431/5450, have the advantages of less external part count and reduced design complexity, as well as limited output capacitor selection. By adding only two or three external components into the standard circuitry, these devices generally work well with aluminum/ceramic output capacitors - Q1 2010 Issue Analog Applications JournalPDF, 2.6 Mb, 档案已发布: Jan 29, 2010
