BD8313HFN
3,5-14 V 1,2 A 1-Kanal-Buck-Wandler

Der synchrone 1,2 A/1,0 MHz-Abwärtsschaltregler BD8313HFN von ROHM stellt eine Abwärtsausgangsspannung her, darunter 1,2, 1,8, 3,3 oder 5 V von 4 Batterien, wie z. B. Li2- oder Li3-Zellen usw., oder eine feste Versorgungsleitung von 5 V/12 V her. Dieser IC ermöglicht eine einfache Herstellung von kleinen Versorgungsleitungen durch eine große Bandbreite an externen Konstanten und ist mit einer externen Spule/einem externen Kondensator ausgestattet, die/der von einem hohen Frequenzbetrieb von 1,0 MHz abgestuft wurde. Die integrierte synchrone Gleichrichtung SW hält 15 V stand. Außerdem ist ein flexibles Phasenkompensationssystem enthalten.
