Sparkfun Buck Converter - 8-20V to 5V/3A

The Buck Converter efficiently transforms an input voltage ranging from 8V to 20V into a stable 5V output at up to 3A (15W), making it ideal for mobile, robotics, or off-grid projects. Its compact design and robust performance ensure a steady power supply, even during fluctuating battery conditions.

This converter is perfect for battery-powered projects, whether you're using Sealed Lead Acid (SLA) batteries, Lithium Iron Phosphate (LiFePO4) packs, or a standard 12V wall adapter. It reliably powers your 5V components, safeguarding them from voltage irregularities.

Operating at an impressive 89% efficiency, this converter minimizes power loss, extending your battery’s runtime. Its high efficiency ensures minimal heat generation, making it suitable for projects where thermal management is a concern.

With an output voltage accuracy of ±1% and an ultra-low ripple of 30mVp-p, it provides clean power, crucial for sensitive microcontrollers, sensors, and USB devices. This ensures that your electronics operate without disruptions or errors.

The converter's built-in thermal performance and protection circuitry eliminate the need for additional heat sinks or complex cooling systems in most applications. Simply connect your power source to the input, and you have a reliable 15W continuous 5V power supply ready to support your demanding electronics.
