  • Product introduction

TPS5450 5,5 V bis 36 V Eingang, 5 A, 500 kHz Abwärtswandler

illustrate

 

Als Mitglied der DC/DC-Reglerfamilie von ™ SWIFT ist TPS5450 ein PWM-Wandler mit hohem Ausgangsstrom, der einen niederohmigen High-Side-N-Kanal-MOSFET integriert. Zu den Merkmalen, die mit dem Substrat aufgeführt sind, gehört ein Hochleistungs-Spannungsfehlerverstärker, der unter transienten Bedingungen eine hohe Regelungsgenauigkeit bietet. eine Unterspannungsabschaltung, um ein Einschalten zu verhindern, bis die Eingangsspannung 5,5 Volt erreicht; Eine interne Langsamstartschaltung ist so eingestellt, dass der Einschaltstrom begrenzt wird. und Spannungs-Feed-Forward-Schaltung zur Verbesserung des Einschwingverhaltens. Using the ENA pin, the shutdown supply current drops to 18μA typically. Other features include an active high start, overcurrent limit, overvoltage protection, and thermal shutdown.

 

characteristic

 

  • Wide input voltage range: 5.5 V to 36 V
  • Bis zu 500 kontinuierliche Ausgangsströme (6 Spitzen)
  • Hoher Wirkungsgrad von mehr als 90 %, ermöglicht durch 110 Meter Integrated MOSFET switch
  • Wide output voltage range: adjustable down to 1.5% to 1.22 V initial accuracy
