DC-DC Converters
i7A
NEW MODEL 400 to 1000W, 9 to 18V, 18 to 32V, 18 to 60V or 28 to 60V Input, Non-isolated DC-DC Buck ConvertersThe i7A series of high-efficiency, non-isolated buck converters delivers scalable power solutions up to 1000W in a compact 1/16th brick pinout, addressing key design challenges such as limited board space, inefficient power delivery, and complex thermal management. With output currents up to 100A and wide input/output voltage ranges, it simplifies various power distribution architectures and part number management while reducing the need to parallel multiple converters.
Its fast transient response and low ripple ensure stable performance, while three thermal configurations—open frame, baseplate, and heatsink—offer flexible cooling options tailored to system requirements. Available with positive or negative logic remote on/off and an optional adjustable OCP current limit threshold, the i7A is suitable for industrial, communications, test and measurement, and battery-powered applications, including mobile robotics.
Features
- Up to 1000W in a 1/16th Brick Footprint
- High Efficiency - Up to 99%
- Wide 0.8 to 8V or 3.3 up to 32V Output Adjustment
- Low Component Count With Minimal External Components
- Minimal Derating Requirements in Low Airflow Environments
- Adjustable OCP, Current Limit Threshold
