Description
IAD dual-output DC/DC converters provide up to 12 watts of output power in an industry-standard package and
footprint. With a maximum case temperature of 85°C, the IAD is well suited for the most demanding applications. The
IAD features 1500 VDC isolation, short circuit, and overtemperature protection, as well as six-sided shielding. The IAD
is available with optional enable and voltage trim pins. Please see the IAS series for single-output applications.
