Description
Features
• Industry-standard package
• Industry-standard footprint
• Fixed-frequency design
• 85 °C case operation
• Optional trim and enable
• Wide-range input
• 1500 V isolation
• Short-circuit protection
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.
