A company developing advanced infrared (IR) illumination solutions for aerospace and defense applications required compact, reliable power conversion to support precision electronics within their imaging systems. Their equipment is often used in environments that demand stable, isolated DC power for sensitive circuits—while operating under wide input voltages and challenging conditions.
Key design goals included:
- Wide 4:1 input range (18–75 VDC) for flexible integration with military and aerospace power systems
- 1,500 VDC isolation to protect critical control and signal electronics
- Compact SIP footprint for high-density layouts
- Continuous short-circuit protection and robust EMI performance for mission-critical reliability
The engineering team selected the MD100BRU series from MicroPower Direct. The MD148S-05BRU model delivers 5V at up to 76% efficiency, features a wide 48V input range, and provides low ripple/noise output. Its compact size, 1,500 VDC isolation, and compliance with EN 55032 Class B EMI standards made it ideal for integration into sensitive IR illumination modules.
By incorporating the MD100BRU, the customer ensured stable, reliable operation for their IR systems—supporting long-term performance and protection in demanding aerospace and defense environments
