The DC-DC Adjustable Boost Converter 4 A (5–32 V to 5–35 V) Module is a step-up switching voltage regulator designed to increase DC input voltage to a higher adjustable DC output level. It operates over a 5–32 V DC input range and provides an output adjustable from 5–35 V DC with a maximum current capability of up to 4 A under suitable thermal conditions. The module uses high-frequency switching technology based on the XL6009 regulator architecture, enabling efficient power conversion with up to approximately 94% efficiency. It is suitable for powering electronic circuits, battery-operated systems, and embedded applications requiring elevated and adjustable DC voltage. The compact PCB design supports integration into space-constrained electronic assemblies.
