Adjustable Buck Converter with Display – 2A, up to 35V

The DC-DC Adjustable Buck Converter 2 A (3.2–40 V to 1.25–35 V) with Display Module is a switching step-down voltage regulator designed to provide a stable and adjustable DC output from a higher DC input source. It supports an input range of 3.2–40 V DC and delivers an adjustable output from 1.25–35 V DC with a maximum output current of up to 2 A (3 A peak). The integrated digital display enables real-time monitoring of input or output voltage for improved system control. It is suitable for laboratory power supplies, embedded systems, LED drivers, and general electronic prototyping requiring adjustable regulated voltage.
