ADUM4120-1ARIZ

ADUM4120-1ARIZ is a 2A isolated, single-channel driver that employs Analog Devices, Inc., iCoupler® technology to provide precision isolation. Combining high speed CMOS and monolithic transformer technology, this isolation component provides outstanding performance characteristics, such as the combination of pulse transformers and gate drivers. The ADuM4120-1 operates with input supplies ranging from 2.5V to 6.5V, providing compatibility with lower voltage systems. In comparison to gate drivers employing high voltage level translation methodologies, the ADuM4120-1 offer the benefit of true, galvanic isolation between the input and the output. Applications include switching power supplies, IGBT/MOSFET gate drivers, industrial inverters, gallium nitride (GaN)/silicon carbide (SiC) power devices.
