Application Notes
- Using TPS5410/20/30/31/50 w/Aluminum/Ceramic Output Capacitors (Rev. C)PDF, 392 Kb, Revision: C, File published: Mar 21, 2007
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
