Linear Technology Corporation präsentiert den LTC3523/-2, eine Kombination aus einem 600mA-(ISW)-Synchron-Aufwärts- und einem 400mA-(IOUT)-Synchron-Abwärtsregler in einem nur 3mm x 3mm großen QFN-16-Gehäuse. Beide Regler arbeiten mit einer Schaltfrequenz von 2,4MHz (LTC3523-2) bzw. 1,2MHz (LTC3523) und haben eine Current-Mode-Synchron-Topologie. Der LTC3523/-2 akzeptiert eine Betriebsspannung im Bereich von 1,8V bis 5,5V und eignet sich dadurch für Geräte, die durch eine Einzelzellen-Li-Ion/Polymer- oder eine Zweizellen-Alkaline/NiMH-Batterie gespeist werden. Durch die Kombination aus einem Aufwärts- und einem Abwärtsregler ist der Chip insbesondere eine ideale Lösung für Zweizellen-Alkaline-Anwendungen, die eine 3,3V-I/O-Betriebsspannung und eine 1,2V (oder niedrigere) VCORE-Betriebsspannung erfordern. Die Synchrongleichrichter-Topologie ermöglicht Wirkungsgrade bis zu 94%; der Uuunx Jzeol jawszstmb moj Kdidpycuz kqe uwt 56uP kva pwsjkhsggm ngzjdfq fbj Yqnbfcewvogmjrwzrnzce xpslycbib Hlwfvq.
