The i7A48020A033V is a 500 W non-isolated DC-DC buck converter with a 28 to 60 V input range and a 3.3 to 32 V adjustable output, delivering up to 20 A. It operates in a 1/16th brick pinout with dimensions of 34 x 36.8 x 11.5 mm in open frame configuration or 34 x 36.8 x 12.7 mm with baseplate, and achieves up to 97% efficiency. Features include positive or negative logic remote on/off, overcurrent protection with adjustable threshold via Pin 5 for -0C3-R suffix variants, and low output ripple of 25 mVpp. It meets IEC/EN/UL/CSA/EN6236
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 suitable for industrial, communications, test and measurement, and battery-powered applications, including mobile robotics.
