The DFRobot 20W Adjustable DC-DC Boost Converter (DFR0123) is a compact step-up power module built around a professional boost IC. It accepts a wide 3–32V input and delivers a precisely regulated 5–35V output at up to ±0.05V accuracy, making it ideal for powering higher-voltage loads from batteries, automotive sources, or low-voltage bench supplies. The 400 kHz switching frequency keeps the design efficient across the full range, peaking at 94% conversion efficiency.
The module features an integrated digital display voltmeter that shows both input and output voltage, complete with a single-button self-calibration routine for accurate readings across the entire voltage range. Terminal blocks mean no soldering iron is required for most setups, while solder pads remain available for permanent installations. Built-in overheating and short-circuit protection safeguard both the module and the connected load during extended or high-demand operation.
