Product introduction

TPS40055-EP Erweiterter synchroner Abwärtsregler mit breitem Eingang

illustrate

Der TPS40055 ist ein synchroner Abwärtswandler mit breitem Spannungseingang (8 V bis 40 V). Die TPS40055-Familie bietet eine Vielzahl von benutzerprogrammierbaren Funktionen, darunter Sanftanlauf, Unterspannungsabschaltung, Betriebsfrequenz, Spannungsvorsteuerung, High-Side-Strombegrenzung und Flexibilität bei der Schleifenkompensation.

Der TPS40055 kann auch mit einem externen Netzteil synchronisiert werden. Der MOSFET-Treiber ist TPS40055 einen externen N-Kanal-High-Side- und Synchron-Gleichrichter-MOSFET (SR) integriert. Drive logic gate reversal circuitry is used to prevent cross-conduction synchronous high-side and synchronous rectifier conduction.

Der TPS40055 verwendet die Spannungs-Feed-Forward-Steuerungstechnologie, um einen breiten (4:1) Eingangsspannungsbereich mit guter Linearitätsregelung und schnellem Ansprechverhalten in der Nähe von Eingangsschwankungen bereitzustellen, wodurch die Schleifenkompensation für konstante Verstärkungs- und Eingangsspannungstransienten vereinfacht wird.
