Description
Product Overview
The 250W 10A DC-DC Boost Converter Module is a high-power, high-efficiency step-up switching regulator designed to convert lower DC voltages into higher, adjustable output voltages. Whether you need to power a laptop from a 12V car battery, drive high-power LED arrays, or create a custom benchtop power supply, this module delivers the performance and flexibility required for demanding applications .
At its core, this module utilizes a non-isolated boost (BOOST) topology with a maximum output power of 250W and a peak output current of 10A . The input voltage range of 8.5V to 48V allows it to accept power from a wide variety of sources, including 12V car batteries, 24V truck electrical systems, solar panels, and 36V industrial power rails. The output is continuously adjustable from 10V to 50V, making it suitable for everything from charging lithium battery packs to powering 36V LED lighting systems .
A standout feature of this module is its dual-mode operation: it functions as both a constant voltage (CV) power supply and a constant current (CC) LED driver. The onboard potentiometers allow you to independently set the output voltage and current limit, making it perfect for charging batteries (where a constant current/constant voltage profile is required) and driving high-power LEDs (where a regulated current is essential to prevent thermal runaway) .
The module achieves a conversion efficiency of up to 96% thanks to its 150kHz switching frequency and high-quality components, including a toroidal inductor and low-ESR capacitors . For enhanced durability, the module is built on an aluminum PCB substrate, which acts as a heatsink to dissipate heat during high-power operation. When running at currents above 6-8A, external cooling (a fan or larger heatsink) is recommended to maintain optimal performance and longevity .
