An industrial electronics manufacturer was developing a compact control module for integration into high-reliability equipment. The application required a rugged, high-efficiency DC/DC converter to deliver regulated power within a tightly confined enclosure, while withstanding wide environmental operating conditions.
Key Design Goals:
15W isolated power in a compact footprint
High efficiency to reduce internal heat buildup
Operation across a wide temperature range
1,500 VDC isolation for circuit protection
The engineering team selected a model from the MI1500RW series, which features a 2:1 input range, up to 91% efficiency, and a compact 1 x 1 inch metal case—ideal for high-density layouts. Its 1,500 VDC isolation and -40°C to +80°C operating range ensured long-term performance in field conditions without derating or additional thermal mitigation.
The module has delivered consistent performance in the field, supporting long-term reliability within a demanding industrial environment. Its compact size and efficiency also helped streamline thermal management and simplify system layout.
