SparkFun has declared another approach to control your tasks, exploiting the adaptability of the USB Power Delivery Standard: an independent USB Type-C power board with three configurable power distribution profiles.
“Traditional power adapters can provide a wide range of current but the voltage stays fixed at 5V,” SparkFun’s Xtopher explains. “With the SparkFun Power Delivery Board’s USB-C connection it has the ability to achieve higher voltages, typically 5-20V and up to 100W of power. The Power Delivery Board uses a standalone controller to negotiate with the power adapters and have them switch to a higher voltage other than just 5V. This uses the same power adapter for different projects rather than relying on multiple power adapters to provide different output voltages.”
The board depends on a STMicroelectronics STUSB4500 USB Power Delivery controller, which takes into consideration the arrangement of power distribution without an outer microcontroller — however, SparkFun cautions, a microcontroller is as yet required for configuration, with settings being saved into a stable space on the controller itself.
The controller board’s input and output voltage vary between 5-20V with output current up to 5A across three end user configurable power delivery profiles. It’s completely certified to USB Type-C Rev. 1.2 and USB Power Delivery Rev. 2.0, and incorporates integrated VBUS voltage checking and PMOS switch gate drivers. Just as solderable pin headers, there’s a particular Qwiic connector for solder free connectivity into SparkFun’s quick-connect I2C ecosystem.
The Sparkfun USB Type-C 5-20V 5A Power Delivery Board is available for $24.95 at www.sparkfun.com
