Linear Technology Corporation präsentiert den LTC3550, eine effiziente, kompakte Power-Management-Lösung für Handgeräte. Der Chip enthält einen Li-Ion/Polymer-Akkulader mit zwei Eingängen und einen wirkungsgradstarken Synchron-Abwärtsregler und besitzt ein flaches, 16-poliges, 3mm x 5mm großes DFN-Gehäuse. Der Linearregler-Akkulader ist zum Laden von Einzelzellen-Li-Ion-Akkus vorgesehen und kann durch einen Netzadapter oder über eine USB-Schnittstelle gespeist werden; die Eingangswahl erfolgt automatisch. Die autonome Betriebsweise des Chips vereinfacht das Design und macht einen externen Mikroprozessor zum Beenden des Ladevorgangs entbehrlich. Der Lader arbeitet mit einem Konstantstrom/Konstantspannungs-Algorithmus; der maximale Ausgangsstrom beträgt beim Betrieb an einem Netzadapter 950mA und beim Betrieb an einer USB-Schnittstelle 500mA. Die Float-Endspannungsgenauigkeit tqowgph b7,8%.
