Wave Step-Down Regulator - VIN: 5-36V, VOUT: 3.3V/5V

The Wave Step-Down Regulator is a compact and highly efficient DC-DC buck mini module, offering configurable 3.3V or 5V output with a wide input voltage range of 5–36V. By default, the module outputs 5V and supports input voltages from 6–36V. For 3.3V output, the onboard resistor can be resoldered, allowing input voltages of 5–36V. Designed for seamless integration, it features a black immersion gold finish and castellated holes for versatile embedding in various applications.



With a switching frequency of 500kHz and up to 90% conversion efficiency, this regulator is capable of delivering up to 4A of continuous current and up to 5A under optimal heat dissipation. Its small size and reliability make it ideal for a wide range of projects.
