Adjustable DC Buck Converter for USB-C Devices
This buck converter accepts a DC input range of 8.2V to 32V and delivers an adjustable output of 3V to 20V at up to 4.8A. It is suited for engineers, hobbyists and technicians who need to power or charge USB-C equipment from higher-voltage sources such as 12V or 24V battery systems. The module includes both a DC jack and screw terminals for flexible wiring.
Synchronous Rectification for Efficient Step-Down
The regulator uses a synchronous rectification scheme to maintain high efficiency across the wide voltage range while supplying large current. In normal operation the circuit steps down voltage with minimal heat rise, keeping thermal load low without active cooling. The compact board measures 10.0 by 27.0 by 10.0 inches and weighs 0.1 lb, allowing it to fit in tight enclosures.
Dual USB Ports with Fast-Charge Detection
A USB-C port and a USB-A port share a quick-charge identification chip that automatically negotiates fast-charging protocols with compatible phones and tablets. Both ports can be used simultaneously only when the USB-A device is connected first, though this disables fast charging. When the USB-C port is negotiating a fast-charge voltage, attaching a 5V load to the USB-A port risks damaging that load.

Questions about this item
How do I wire the KEHIPI buck converter to a 24V source so the USB-C port delivers 12V at up to 4.8A?
Connect the 24V supply to the DC input terminals observing polarity, then use the onboard adjustment to set the output to 12V; the USB-C port will then provide up to 4.8A for fast charging.
What ongoing check does the step-down regulator need after months of continuous operation?
Periodically verify the output voltage with a multimeter and ensure terminal screws remain tight, as vibration can loosen connections and cause drift over time.
At what input voltage does the converter hit its thermal limit first during sustained 4.8A loads?
The unit reaches its thermal ceiling quickest at the maximum 32V input while delivering 4.8A, because the voltage drop across the regulator is greatest there.
