Description

The LM2596 DC-DC Buck Converter Step-Down Power Supply Module is a high-performance switching regulator designed for efficient voltage reduction and stable power delivery. Built around the popular LM2596 chip, this module offers both fixed and adjustable output voltage options, making it ideal for a wide range of applications including Arduino, robotics, embedded systems, and DIY electronics projects. Capable of delivering up to 3A output current with excellent line and load regulation, it ensures stable performance even under varying loads.

Operating at a high switching frequency of 150kHz, the LM2596 allows the use of smaller filter components compared to lower-frequency regulators, resulting in a more compact design. The module features a high-precision potentiometer for fine voltage adjustment, and its high efficiency of up to 92% significantly reduces power loss compared to traditional linear regulators. For sustained high-power applications (above 2.5A or 10W), a heatsink is recommended to maintain optimal performance.

Applications:

  • Power supply for Arduino, Raspberry Pi, and other development boards

  • Voltage regulation in embedded systems and robotics

  • Step-down converter for battery-powered devices

  • DIY electronics projects requiring adjustable DC output

Features:

  • Wide input voltage range: 3V–40V

  • Adjustable output voltage: 1.5V–35V

  • High efficiency: up to 92%

  • Rated current 2A, max 3A (with heatsink)

  • High-precision voltage adjustment

  • Compact and lightweight design

  • Short circuit and current limit protection
