应用须知
- Design Procedure for the TPS54122PDF, 386 Kb, 档案已发布: Nov 4, 2013
This application report details the design procedure of a low-noise, 3-A power supply with the integratedswitcher and low-dropout (LDO) regulator of the TPS54122. The designer must know a few parameters inorder to start the design process and typically determines them at the system level. - A Topical Index of TI LDO Application Notes (Rev.
