DC-DC Converter Module No name LTC3780 — adjustable boost/buck regulator module

DC-DC Converter Module No name LTC3780 — adjustable boost/buck regulator module is a compact power conversion board based on the LTC3780 controller IC. It provides adjustable step-up and step-down regulation between input and output rails, enabling a stable DC output over a range of input voltages. The module is designed for use in electronics projects, battery-powered systems and laboratory prototyping where reliable voltage regulation and flexibility are required.

Advantages

The module combines boost and buck functionality in a single board, allowing seamless voltage conversion above or below the input level without swapping components. It delivers adjustable output voltage with fine control through onboard potentiometers, supports efficient power conversion for reduced heat dissipation, and includes common protective features found in regulator modules. The compact form factor and standard pinout make the module suitable for bench testing and integration into custom circuits.

Suitable for

• Powering electronic projects from variable battery packs or adapters
• Charging and maintaining battery systems with controlled voltage
• Laboratory experiments, prototyping and bench power supplies
• Embedded systems that require regulated DC rails from fluctuating sources

Key specifications

• Operating mode: adjustable boost (step-up) and buck (step-down) regulation
• Input voltage range: suitable for a broad range of DC input sources (refer to module label or documentation for exact limits)
• Adjustable output voltage: user-settable via onboard adjustment components
• Power conversion topology: switching regulator for higher efficiency compared to linear regulators
• Typical applications: battery charging, voltage regulation for electronics, prototyping power supply

How to use

Connect the input supply to the module input terminals observing correct polarity, and connect the load to the output terminals. Before connecting sensitive devices, set the desired output voltage using the onboard adjustment control while monitoring with a multimeter. Ensure input voltage stays within the safe operating range of the module, and allow for adequate cooling under higher load conditions. Follow standard safety practices: wire securely, avoid short circuits, and verify polarity and voltage before applying power to downstream electronics.

Usage recommendations

For reliable operation, use appropriate input decoupling and secure wiring. Test the module under expected load conditions and measure output voltage and temperature during initial operation. When used for battery charging, implement proper charge management suited to the battery chemistry; the module provides regulated voltage but not necessarily full charge-cycle management unless additional circuitry is used.
