BD9S111NUX-C
Synchroner 2,7-V- bis 5,5-V-Eingang- 1A-Einkanal-DC/DC-Abwärtswandler für die Automobilindustrie

Der BD9S111NUX-C ist ein synchroner DC/DC-Abwärtswandler mit integrierten Leistungs-MOSFETs mit niedrigem Durchlasswiderstand. Es kann Strom bis zu 1A liefern. Durch die hohe Schaltfrequenz von 2.2MHz kann eine kleine Induktivität eingesetzt werden. Es handelt sich um einen DC/DC-Wandler mit Stromregelung, der sich durch ein schnelles Einschwingverhalten auszeichnet. Er hat einen integrierten Rückkopplungswiderstand, der die Ausgangsspannung auf %v (BD9S110NUX-C)/1,8V (BD9S111NUX-C) setzt und eine eingebaute Phasenkompensationsschaltung. Anwendungen können mit wenigen externen Komponenten erstellt werden.
