IAS DC/DC Series Data Sheet
Description
IAS DC/DC converters provide up to 12 watts of output power in an
industry-standard package and footprint. With a maximum case
temperature of 100°C, the IAS is well suited for the most
demanding applications. The IAS features 1500 VDC isolation,
short circuit and overtemperature protection, as well as six-sided
shielding. The IAS is available with optional enable and voltage
trim pins. Please see the IAD Series for dual-output applications.
