Nowadays, with the popularity of USB-C PD adapters in the past few years, the PD protocol adapters in the hands of consumers are becoming more and more common. How to make the Microsoft Surface charger cable support the use of PD adapters for fast charging? Add a PD protocol power-taking chip at the power receiving end - LDR6328 is perfectly compatible with PD adapters on the market and supports 
different voltage outputs.
1 Overview
LDR6328 is a communication chip compatible with USB PD and QC developed by Ledry Technology Co., Ltd. for the USB PD protocol and Qualcomm Quick Charge (referred to as QC) protocol. The input terminal is mainly connected to the adapter of PD and QC, and the output terminal is configured to output a fixed voltage. The LDR6328 draws power from an adapter that supports USB PD and QC protocols, and then supplies power to the device. For example, the adapter can be configured to output the required power to supply power to the wireless charger device.
