20W Adjustable DC-DC Boost Converter with Digital Display

The 20W Adjustable DC-DC Boost Converter with Digital Display is a compact step-up power module designed to step up low-voltage DC sources into an adjustable 5V–35V output. Featuring an onboard digital voltmeter, high switching frequency, and up to 94% efficiency, it is an essential tool for makers, students, and hobbyists building custom power supplies or battery-powered projects.

Wide step-up voltage range

This module converts input voltages from 3V–32V into a regulated output between 5V and 35V, with peak input current handling up to 4A. Its 400kHz switching frequency delivers stable power transfer while maintaining a compact footprint for embedded applications.

Integrated digital voltmeter

An onboard digital display provides real-time monitoring of either the input or output voltage with an accuracy of ±0.05V. It features built-in self-calibration with adjustment steps from -5 to +5, operating whenever the input voltage is 5V or higher.

High efficiency and safety protections

Reaching up to 94% conversion efficiency, the module minimises energy loss and thermal build-up during operation. Integrated short-circuit and overheating protection mechanisms protect your connected electronics against unexpected faults.

Flexible wiring options

The board features screw terminal blocks for quick, tool-free prototyping alongside dedicated solder pads for permanent installations. It operates reliably across an industrial temperature range of -40°C to +85°C.

Versatile prototyping applications

This step-up regulator is well suited for DIY bench power supplies, boosting battery voltages, and automotive notebook adapters. It also delivers dependable power conversion for portable devices and industrial control electronics.
