Briefly describe the experience of LDR6028 in the PD chip of Type-C mobile phone accessories (a small package PD protocol chip carefully crafted in the wireless lapel microphone of the mobile phone and listening while charging)

LDR6028 is a small-package PD protocol chip carefully crafted in the current LDR-PD series for mobile wireless lavalier microphones and charging while listening. It is launched on the basis of Type-C mobile phone fast charging chip LDR6023C and the needs of platforms such as live broadcasting. .
