LTC3559: Monolithischer USB-Linear-Akkulader mit wirkungsgradstarkem Zweifach-Synchron-Abwärtsregler

(PresseBox) (Ismaning, )
Linear Technology Corporation präsentiert den LTC3559, eine wirkungsgradstarke Multifunktions-Power-Management-Lösung für Handgeräte. Der LTC3559 enthält einen Li-Ion/Li-Polymer-Akkulader und zwei wirkungsgradstarke Synchron-Abwärtsregler; der Chip besitzt ein flaches, nur 3mm x 3mm großes DFN-Gehäuse. Der Linearregler-Akkulader kann beim Betrieb an einem Netzadapter bis zu 950mA und beim Betrieb an einer USB-Schnittstelle bis zu 500mA Ausgangsstrom liefern. Der Chip bietet ein hohes Maß an USB-Funk¬tio¬nali¬tät wie z. B. programmierbarer Ladestrom (20%/100%), SUSP-Anschluss für Shutdown/Enable und /CHRG-Anschluss zur Signalisierung von vier verschiedenen Ladezuständen. Die autonome Betriebsweise des Chips vereinfacht das Design und macht einen externen Mikroprozessor zum Beenden des Ladevorgangs entbehrlich. Die Float-Endspannungsgenauigkeit beträgt ±0,4%.
