Freescale Semiconductor Application Note Document Number: AN3295 Rev. 0.2, 02/2010 External Component Recommendations for the MC13783 Reference Design by: Power Management and Audio Application Team 1 Introduction The recommendations for external components used for a reference or application design implemented with the MC13783 are outlined in this document. The MC13783 is a power management and user interface (PMUI) integrated circuit that can be used in Freescale's 3G cellular platforms or other portable handheld applications such as non 3G protocol cellular, gaming devices, personal media players, remote controlled toys, etc. The purpose of this application note is to provide the suggested parts list to design with the MC13783. The parts listed are suggested, but not mandated. Other suitable parts may be available or even preferred for application optimizations. It is recommended to follow the guidelines of the MC13783 data sheet and to utilize conventional judgment on part selection as well as for component placement and board layout. © Freescale Semiconductor, Inc., 2006–2010.
