Hocheffiziente Schaltregler

Als RECOM im Jahr 2005 den ersten R-78 Schaltregler entwickelt hat, wurde schnell klar, welch großes Potenzial in diesem Produkt steckt. Plötzlich konnten ineffiziente und wenig zuverlässige Längsregler mit einem DC/DC-Wandler ersetzt werden, der dank bis zu 97% Wirkungsgrad einen Kühlkörper verzichtbar machte. Da er zugleich Pin-kompatibel war, konnte er problemlos in bestehende Schaltungsdesigns integriert werden. Im Laufe der Jahre wurde das R-78-Portfolio schrittweise mit höheren Ausgangsströmen (bis zu 2A) oder breiteren Eingangsspannungen bis zu 100V erweitert, ohne von diesem platzsparenden SIP3-Design abzuweichen. Aufgrund seines Erfolgs wurde der R-78 vielfach nachgeahmt; Käufer sollten jedoch vor Fälschungen und minderwertigen Alternativen gewarnt sein.

RECOM hat das Konzept der nicht-isolierten Schaltregler weiterentwickelt und bietet Produkte in anderen „Power Module“-Formaten unter Einsatz von 3D power packaging®-Techniken an. Beispiele sind der hocheffiziente, flache RPM-Serie Point-of-Load (PoL) Wandler im DOSA-Footprint, die RPX-Serie mit 1 bis 3A in einem flachen QFN-Gehäuse sowie das RPL-3.0-Modul mit nur 1,45mm Bauhöhe und 3 x 3mm Footprint mit LGA-Anschlüssen. Der RBB10 Buck-Boost-Wandler ist ebenfalls erhältlich und bietet eine einstellbare Ausgangsspannung von 1V bis 5,5V bei einer Eingangsspannung, die über oder unter der Ausgangsspannung liegen kann.

Zur schnellen Überprüfung der Produktleistung unter spezifischen Designbedingungen bietet RECOM Evaluierungsboards für seine Power-Module an.
