ADUM5403

四通道， 2.5千伏隔离带集成DC - DC转换器 Quad-Channel, 2.5 kV Isolators with Integrated DC-to-DC Converter

GENERAL DESCRIPTION

The ADuM5401/ADuM5402/ADuM5403/ADuM54041 are quad-channel digital isolators with isoPower®, an integrated, isolated dc-to-dc converter. Based on the Analog Devices, Inc., iCoupler® technology, the dc-to-dc converter provides up to 500 mW of regulated, isolated power at either 5.0 V or 3.3 V from a 5.0 V input supply, or at 3.3 V from a 3.3 V supply at the power levels shown in Table 1.
