Boost Converter Module

VersionLicense

The Boost Converter Module is a compact, adjustable DC–DC step-up (boost) regulator designed to increase a lower input voltage to a higher output voltage. It is powered by the TPS61023 high-efficiency switching regulator from Texas Instruments, enabling reliable operation even from low-voltage sources such as LiPo batteries or solar panels.
A multi-turn potentiometer is included for precise output voltage adjustment, making the module ideal for battery-powered applications and compact embedded systems.

This makes it ideal for powering circuits from LiPo cells, USB power banks, solar panels, and other low-voltage sources in embedded projects and prototyping.

Quick Start

  1. Wire up
    • Connect your lower-voltage source to VIN + and VIN –.
    • Connect your load to VOUT + and VOUT – (common ground).
  2. Adjust output
    • Use a small screwdriver to turn the potentiometer clockwise to raise voltage, counter-clockwise to lower.
    • Monitor the output with a multimeter for precise setting.
  3. Test under load
    • Apply a typical load and verify the voltage remains stable.

Tip: Always start with the potentiometer turned fully counter-clockwise (lowest voltage) before applying power. Then slowly dial up to your target voltage while monitoring with a meter.
