Whadda UK LM2596S DC-DC Step-Down Buck Converter Module
Whadda LM2596S DC-DC step-down buck converter module, 3V to 40V input, 1.25V to 35V adjustable output, 2.5A maximum continuous current.
The Whadda UK LM2596S DC-DC Step-Down Buck Converter Module is a fully adjustable power regulator with a maximum continuous output current of 2.5A. Based on the popular LM2596S switching regulator chip, it steps down a higher input voltage to a stable, lower output voltage for a wide range of electronics projects.
Overview
This module accepts an input voltage range of 3V to 40V DC and provides a smooth, adjustable output from 1.25V up to 35V DC. Its switching design offers higher efficiency than traditional linear regulators, reducing power dissipation and heat generation. A small onboard multi-turn potentiometer makes voltage adjustment precise and straightforward.
Key Features
- High-efficiency switching design that reduces power dissipation and heat generation
- Wide input voltage range of 3V to 40V DC
- Adjustable output from 1.25V up to 35V DC
- Maximum continuous output current of 2.5A
- Onboard multi-turn potentiometer for precise voltage adjustment
- Compact footprint of approximately 43 mm x 33 mm x 15 mm
- Standard 0.1-inch pitch pin headers for connection to breadboards, PCBs, or wire terminals
Applications
Suitable for converting power from sources such as 12V car batteries, 24V supplies, or variable bench supplies down to circuit voltages such as 5V for Arduino or 3.3V for sensors. It can power motors, LED strips, microcontrollers, and other demanding components, and is well suited to battery-powered or energy-sensitive applications.
Important Usage Note
For applications where power dissipation exceeds approximately 10W, an external heatsink is recommended to ensure optimal performance and long-term reliability. A heatsink is not included.
This module is suited to hobbyists, makers, and engineers working with Arduino, Raspberry Pi, robotics, and custom electronic designs. Choose the Whadda UK LM2596S DC-DC Step-Down Buck Converter Module when you need an adjustable step-down power solution for prototypes, enclosures, and permanent installations.
