BMT ADJ DC/DC Buck Module LM2596HV 4.5-40V 3A Step-Down Converter

The BMT Adjustable DC-DC Buck Module LM2596HV is a compact and efficient step-down voltage converter designed for a wide range of DC input voltages. It allows you to adjust the output voltage from 3V to 35V, making it ideal for powering microcontrollers, sensors, motors, and other electronics from higher-voltage sources. This module supports a continuous output current of 2A with a peak capability of up to 3A and offers a maximum output power of 15W.

The module uses the LM2596HV IC, known for its high efficiency (up to 92%), low static consumption (approx. 6 mA), and stable performance over a wide temperature range (-40 C to +85 C). The output voltage is adjusted via the onboard potentiometer while monitoring with a multimeter, allowing precise voltage tuning for sensitive electronics.

This step-down module is small (45 × 24 × 11 mm) yet powerful, with input voltages from 4.5V to 40V (with a brief tolerance up to 50V). It features reliable industrial-grade components and can be directly mounted on a PCB via welding or pin headers.

Perfect for hobbyists, makers, and engineers, this module ensures reliable, efficient, and adjustable DC power for a wide range of electronic applications.
