Introduction

1 Introduction
As portable electronic devices such as smartphones, tablets, and laptops require faster charging, the Power
Delivery (PD) technology is designed to provide the fastest charging possible through a USB Type-C (USB-C)
cable. The USB PD Standard Power Range (SPR) standard defines the maximum power to deliver over a USB-C
cable up to 100 W. This allows for providing multiple USB-C ports
can charge a wide range of devices such as smartphones, gaming laptops, power tools, and e-bikes.
However, these new requirements for higher power and multi-port have presented challenges for the converter
topologies used till now. Considering a few factors such as electromagnetic compatibility, power factor
correction, standby power, and average efficiency ensures that the chargers and adapters are effective and
efficient. The size (power density), load sharing, and scaling up multiple ports became critical factors for design
engineers and end-users. The power efficiency of USB-C chargers and adapters is a crucial role in determining
their power density. Therefore, converter topology, usage model, integration, and flexibility of controller
functionalities are all key factors to consider when selecting the right adapter architecture for the needs.
Figure 1 shows a typical block diagram of a multi-port adapter. The front-end AC-DC converter produces the
requested output voltage. On the other hand, the buck converter (connected at the output of the AC-DC
converter) ensures that the defined USB-C PD specifications and performance are achieved for multi-port
adapter applications. Figure 1

Infineon provides a comprehensive solution for both sections of adapters, i.e., AC-DC and buck converters.
Specifically, for AC-DC conversion, Infineon's EZ-PD™ PAG1x-based solution, along with the EZ-PD™ CCG7DC-
based buck converter, ensure compatibility with USB PD/Programmable Power Supply (PPS) standards. The
EZ-PD™ CCG7DC supports a dual PD/PPS port, capable of controlling two buck controllers with integrated
drivers, which makes it an ideal choice for dual or multi ports (multiples of 2) applications.
