应用须知
- Using the bqSWITCHER, bq24115, as a Nickel ChargerPDF, 151 Kb, 档案已发布: Jan 5, 2007
This application report describes the combination of the bqSWITCHERв„ў bq24115 charge management device and the bq2002 battery charge controller to provide a high-efficiency-switching charging solution for nickel battery packs. - Power Dissipation Analysis & Circuit Design for Sync Switching Battery ChargerPDF, 402 Kb, 档案已发布: May 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 - Implementations of Battery Charger and Power-Path Mgmt System Using bq241xxPDF, 752 Kb, 档案已发布: 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, 档案已发布: Jan 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.
