Anwendungshinweise

  • Power Dissipation Analysis & Circuit Design for Sync Switching Battery Charger
    PDF, 402 Kb, Datei veröffentlicht: 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
