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, and 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.

† MTBF predictions may vary slightly from model to model.
Specifications typically at 25°C, normal line, and full load,
unless otherwise stated.
Soldering Conditions: I/O pins, 260°C, ten seconds; fully
compatible with commercial wave-soldering equipment.
Safety: Agency approvals may vary from model to model.
Please consult factory for specific model information.
Units are water-washable and fully compatible with
commercial spray or immersion post wave-solder washing
equipment.
