The LM2596 Buck Converter Voltage Regulator is a DC-to-DC step-down module designed to convert an input voltage range of 3.2V to 35V to an adjustable output voltage of 1.25V to 30V. This module utilizes the LM2596 IC, a switching regulator capable of delivering a maximum output current of 3A, though continuous operation is recommended at 2A or less to ensure stability and prevent overheating. The module features a potentiometer for output voltage adjustment, a built-in LED indicator for power status, and a compact design measuring approximately 43mm x 21mm x 14mm. It operates with a switching frequency of around 150kHz, offering a typical efficiency of up to 92% depending on input/output voltage differential and load. The device supports a temperature range of -45°C to +85°C and includes basic protection features such as over-temperature and short-circuit safeguards.

Key Features:

  • Input Voltage: 3.2V to 35V DC – Suitable for a variety of power sources, including batteries and adapters.
  • Output Voltage: 1.25V to 30V DC, adjustable via potentiometer – Requires input voltage to be at least 1.5V above the desired output.
  • Output Current: Maximum 3A, recommended continuous use at 2A or below – Heat dissipation recommended for loads above 10W.
  • Dimensions: Approximately 43mm x 21mm x 14mm – Compact for DIY or embedded applications.
  • Switching Frequency: Approximately 150kHz – Balances efficiency and size.
  • Efficiency: Up to 92% (varies with load and voltage differential) – Performance depends on operating conditions.
  • Operating Temperature: -45°C to +85°C – Wide range for diverse environments.
  • Protection: Includes over-temperature and short-circuit protection – Effectiveness varies with usage.
