Using TPS5410/20/30/31/50 w/Aluminum/Ceramic Output Capacitors (Rev. C)

As internally compensated devices, the wide input step-down SWIFT™ 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. This application report shows the step-by-step design procedures when using aluminum/ceramic output capacitors with the wide input SWIFT™ DC/DC converters. Two design examples are provided to better understand both procedures.
