CH224K-based adjustable voltage 6P-PRO

Overview

The output
supports the PD fast charging protocol and can be configured to output five voltages: 5V, 9V, 12V, 15V, and 20V.
The module features
a simple circuit, few components, easy soldering, and a small board area. It uses five 1206 resistors to shunt the VDD and VBUS terminals, solving the heat generation problem. The

configuration method is shown in the silkscreen diagram below. First, connect a fast charging adapter that supports the PD protocol, and then configure the different voltages
according to the silkscreen instructions: 5V , 9V , 12V , 15V, and 20V.

Readme

Note: Due to the limited number of components and the small board size, component identification numbers are not included.
Recommendation: Use LCSC EDA soldering aids for soldering assistance, or add component identification numbers before soldering.
Note: This DC-DC module has a fixed 5V output; the actual output is slightly higher, approximately 5.08V. If you need to adjust the output voltage, check if a higher voltage-rated output capacitor is required.
Replica Cost: Less than 10 RMB
