ADuM52xx Dual Channel 2.5kV Isolators with DC-DC Converter, Analog Devices
A range of dual-channel Digital Isolators incorporating an integrated DC-to-DC converter from Analog Devices. The isoPower® converter uses high frequency switching elements to transfer power through its transformer without an isolated DC-to-DC converter. Logic signal isolation is achieved using Analog Devices iCoupler® technology with a chip scale transformer. The integrated result is a complete, compact solution providing complete isolation.
