Abstract
This purpose of this study is to propose the characteristics analysis of the PCB pattern designed two modes for the output voltage value on the PMIC through converting the limited voltage value inputted from a battery. The PCB design technology has been undergoing difficulty in getting the related technology in a domestic market because of increasing EMI/EMC, Cross-talk, Impedance. And it requires to have the appropriate clearance between the patterns and the technology of PCB pattern width with a amperage according to various uses. The study carried out the characteristics analysis of the PCB pattern designed from a direct output method without a capacitor[mode1], to an output method through a capacitor[mode2] for PMIC output voltage value. Besides, we calculated the pattern width with a amperage using the equation suggested by IPC-2221, presenting the right way of the layout design to analyze the trouble with the test. Therefore, this study is expected to contribute not only to applying the PMIC design for the mobile panel power supply, but also helping the design and application technology in various areas such as car control, camera, note-book, computer, PDA, etc.
