A high-performance non-isolated step-down converter allows voltage reduction from 4 to 38V to adjustable 1.25 to 36V (output voltage will be equal to or lower than the input voltage). It provides a continuous output current of 5A and can handle up to 8A with active cooling, making it suitable for demanding applications. With a maximum power of 250 W and efficiency up to 92%, it minimizes energy losses. The compact design with dimensions of 60 × 37 × 27 mm facilitates integration into electronic systems. The product requires professional installation.
