The i7A4W033A033V is a 500W non-isolated buck converter with an input voltage range of 18 to 60 Vdc and an output voltage range of 3.3 to 24 Vdc at up to 33 A. It operates with 97% efficiency, features a 1/16th brick pinout measuring 34 × 36.8 × 11.5 mm in open-frame configuration, and supports remote on/off with positive logic. The device includes overcurrent protection, adjustable output voltage, and 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.
