DC-DC 35W Buck Boost Converter

The DC-DC 35W Buck Boost Converter is a versatile and efficient power module designed for applications requiring both step-up and step-down voltage regulation. With an input voltage range of 5.5–30V and an adjustable output voltage of .5–30V, this converter is ideal for powering sensitive electronics, battery charging, and portable devices where stable voltage is critical.

Capable of delivering a long-term stable output current of 3A (and up to 4A with enhanced heat dissipation), the converter provides a maximum output power of 35W under natural cooling and up to 50W with additional heat dissipation. The module features precise voltage and current display resolutions (.01V and .002A, respectively), allowing for accurate monitoring and adjustment. With a conversion efficiency of around 88%, it ensures minimal energy loss during operation.

The DC-DC 35W Buck Boost Converter is equipped with advanced protection features, including input reverse protection, output anti-backflow, and short circuit protection. Soft start functionality helps prevent failure when starting modules with high power and load. The module also includes undervoltage protection, activating when the input drops below 4.7V.

User-friendly controls include two buttons: IN/OUT for switching between input and output voltage display, and ON/OFF for toggling the output state. Potentiometers allow for precise adjustment of current (CC) and voltage (CV), with indicator lights for output status and constant current mode. The compact design (66 x 48 x 21mm) and lightweight construction (46g) make it easy to integrate into a variety of setups.
