BD8967FVM
BD8967FVM
4,5–5,5 V 0,8 A 1-Kanal-Buck-Wandler
ROHM's höchst effizienter Zweikanal-Abwärts-Schaltregler BD8967FVM / 8961NV ist ein Netzteil, das für Niederspannung von 3,3 Volt bei 5 Volt Schaltkreisen gemacht wurde. Höchst effizient dank synchronem Gleichrichter. Setzt ein Steuersystem mit Strommodus ein, um ein schnelles Einschwingverhalten bei plötzlichen Lastveränderungen zu garantieren.
