Linearer USB-Power-Manager mit drei integrierten Abwärtsreglern sorgt für automatische Wahl der Spannungsquelle und steuert das Laden des Akkus

(PresseBox) (Ismaning, )
Linear Technology Corporation präsentiert den LTC3557, eine Multifunktions-Power-Management-Lösung für Geräte, die durch einen Li-Ion/Polymer-Akku gespeist werden. Der LTC3557 vereint in sich einen linearen PowerPath™-Manager, einen autonomen Akkulader, eine "ideale Diode", drei wirkungsgradstarke Synchron-Abwärtsregler und einen "Always-on"-LDO in einem flachen, nur 4mm x 4mm großen QFN-Gehäuse. Der PowerPath-Manager sorgt für unterbrechungsfreies Umschalten zwischen mehreren Eingangsspannungsquellen und der Last. Der lineare Akkulader liefert beim Betrieb an einem Netzadapter bis zu 1,5A Ausgangsstrom und beim Betrieb an einer USB-Schnittstelle bis zu 500mA; das ermöglicht kurze Ladezeiten. Die drei Synchron-Abwärtsregler im LTC3557 erlauben Tastverhältnisse bis zu 100% und können Ströme bis zu 600/400/400mA liefern. Bir Bqcpbgmdamfbxusgpc ovmj wfn pletl zk 8,3Y avfiwtxdwwt.
