1.1 USB Type-C Power Delivery Introduction

USB Type-C is the newly introduced and powerful interconnect standard for USB. When paired with the new Power Delivery (PD) specification, Type-C offers enhancements to the existing USB 3.1 interconnect that lower the cost and simplify the implementation of power delivery over USB.

The USB Type-C connector combines multiple USB connectors – Micro-B, Type-A, and Type-B – in a reversible connector measuring only 2.4mm in height, as shown in Figure 1-1.

With PD specification, the USB Type-C connector can deliver up to 240W. This enables a wider range of applications to operate using USB, as shown in Figure 1-2.
