DFRobot DFR0205 is a compact and efficient step-down DC-DC converter module with up to 25 W of power, allowing adjustment of the supply voltage to meet the needs of various electronic components. With a voltage regulation function, a quick 5 V selection switch, and an Ovout interface, it enables simultaneous power delivery to components with different voltage requirements. Ideal for prototyping, mobile projects, automation systems, and IoT applications.
Step-down (Buck) switching converter module with a maximum output power of 25 W, designed to convert a DC input voltage from 3.6 V to 25 V into a regulated output voltage ranging from 3.3 V to 25 V. It is intended for powering components that require a stable voltage lower than the input supply. Operating at a switching frequency of 350 kHz, it provides a constant output current of 5 A at 5 V. Ideal for rapid prototyping, the module offers three output interfaces and an additional source voltage output (Ovout), which exposes the raw input voltage. The ON/OFF function, controllable via microcontroller or digital signal, allows easy power management in complex circuits.
