## 400W-1000W, 9-18V, 18-32V, 18-50V or 28-60V Input Non-Isolated Step Down DC-DC Converter 

The 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 ideal for industrial, communications, test and measurement, and battery-powered applications, including mobile robotics.

## **Typical Application Circuit** 

- Note 1. Certain model numbers have redundant input (9, 10) and/or output (11, 12) pins. Please refer to the PIN assignment table on page 7. 2. The input and output capacitor values can vary depending upon the application requirements. 

3. Output voltage TRIM resistor “Rup” and OCP/Current Limit Adjust resistor, “Ritrim” should be connected to the i7A module as close as possible.

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
