CIC CH224K Breakout - USB Power Delivery Decoy Breakout
Overview
The CH224K integrates multiple fast charging protocols such as USB PD3.0/2.0, BC1.2 and other boost fast charging protocols on a single chip.
With the USB-PD Decoy, a USB-C power adapter can be used as a power supply with the option of selecting different output voltages via DIP switches. It is based on the cheap and easy-to-use CH224K multi-fast charging protocol power receiving chip.
The Power-Good LED lights up when the selected voltage has been successfully negotiated with the USB-C power adapter and is present at the output. The voltage can also be changed during operation.
