The LM2596 Adjustable DC-DC Step Down Buck Converter Module is a proven industrial-grade voltage step-down board based on the LM2596 switching regulator IC, accepting input from 4V to 35V and providing an adjustable output from 1.25V to 30V at up to 3A continuous current — the widest input and output voltage range of the commonly available buck converter modules, making it suitable for a broader range of power sources and output requirements than more compact alternatives. This lm2596 buck converter is the established choice for students reliable step-down conversion.
The lm2596 dc dc buck converter’s 150kHz switching frequency is lower than newer compact buck ICs, which means the board uses larger external components but gains stability at full continuous load and in temperature extremes — the module is rated from -40°C to 90°C, covering industrial, outdoor, and automotive applications in India where operating temperature ranges can vary significantly.
The lm2596 step down buck converter’s 92% peak efficiency keeps heat generation low at typical loads across this wide operating range. This dc dc lm2596 converter is ideal for industrial Arduino automotive and wide-input voltage step-down projects. StemVolt offers fast and reliable delivery with trusted service support.
