USB PD Controller

A PD (Power Delivery) charger is a fast-charging device based on the USB-PD protocol, typically featuring a USB-C interface for power transmission. By communicating with PD-compliant terminal devices, it can flexibly adjust voltage and current within the range of 3.3V–48V and 0.02A–5A, with a maximum output power of up to 240W. This "intelligent regulation" allows a single PD charger to be compatible with multiple terminals such as mobile phones, tablets, and laptops, truly achieving "one charger for multiple uses" via a USB PD controller.
