500W 10A DC-DC Boost Converter Module – High-Power Step-Up Voltage Regulator, Constant Current LED Driver, Mobile Power Supply, Non-Isolated Boost Circuit

Description

Product Overview

The 500W 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, create a custom benchtop power supply, or charge lithium battery packs, 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 input current of 15A and a maximum output power of up to 500W. 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. 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 8-10A, external cooling (a fan or larger heatsink) is strongly recommended to maintain optimal performance and longevity .

Key Features

• High Power Output: Capable of delivering up to 500W of output power with a maximum input current of 15A (output current up to 10A, derate based on input/output voltage differential) .

• Wide Input & Output Range: Accepts DC input from 8.5V to 48V and provides an adjustable output from 10V to 50V .

• Constant Voltage (CV) + Constant Current (CC) Mode: Functions as both a standard voltage regulator and a constant current LED driver. Ideal for charging batteries (CV/CC profile) and driving high-power LEDs .

• High Conversion Efficiency: Achieves up to 96% efficiency, minimizing power loss and heat generation. Operating frequency: 150kHz .

• Adjustable Output via Potentiometers: Multi-turn potentiometers allow for precise, independent adjustment of output voltage and constant current limit .

• Built-in Protection Features: Includes overcurrent protection (OCP) and input reverse polarity protection to safeguard the module and your connected devices .

• Robust Construction: Built on an aluminum PCB substrate for enhanced heat dissipation. Includes 4 mounting holes (3mm) for secure installation .

• Parallel Operation Capability: Two modules can be connected in parallel to increase output current (e.g., two modules each set to 5A for a total of 10A) .

• Compact Form Factor: Small footprint (approx. 70mm × 42mm × 13mm) and lightweight (approx. 50g) allows for easy integration into portable projects .
