Notas de aplicación
- Power Dissipation Analysis & Circuit Design for Sync Switching Battery ChargerPDF, 402 Kb, Archivo publicado: mayo 31, 2005
The bqSWITCHER(TM) (bq24100/03/05/08/13/15) is a highly integrated, switch-mode, Li-ion and Li-polymer battery charger IC. With two power MOSFETs, the gate drivers, and the controller fully integrated in the chip, the circuit design as well as the PCB layout has been appreciably simplified. However, it is still important to have a good understanding of the charger circuit design, layout principles - Extending Single Input Charger to Dual Input Applications (Rev. A)PDF, 256 Kb, Revisión: A, Archivo publicado: sept 21, 2009
- Implementations of Battery Charger and Power-Path Mgmt System Using bq241xxPDF, 752 Kb, Archivo publicado: jun 6, 2006
This application report presents four system topologies that can be used to fully implement a portable power management system solution using the bqSWITCHERв„ў. Test results and the advantages and issues of each topology are discussed. - Drive High Current LEDsPDF, 437 Kb, Archivo publicado: enero 25, 2007
This application report presents high-current LED driving requirements that use the TI integrated boost converter IC TPS6106x and integrated buck converter IC bqSWITCHERв„ў (bq2410x/11x/12x). Step-by-step design procedures, measurement results, and two dimming methods are provided and discussed.
