LTC1871 DC Step Up Booster Converter 3-35V to 3.5-35V + LED Voltmeter

The LTC1871 DC-DC boost converter is a high-efficiency power module designed to step up input voltage from 3–35V to an adjustable output of 3.5–35V. The output voltage is always equal to or higher than the input voltage.

It features a built-in LED voltmeter that allows monitoring of input and output voltage with a simple switch, eliminating the need for external measuring tools.

With efficiency up to 96% and low ripple output, the module ensures stable performance even under higher loads.

Suitable for Arduino projects, automotive power systems, LED applications, and DIY regulated power supplies.
