USB power delivery
For convenient, lightning-fast charging
After premiering in the mid-1990s, USB quickly became the bus of choice for quick data communication. Today, it’s evolved to also provide power, what’s known as USB power delivery (USB PD). USB PD is a fast charge protocol for a wide range of devices. Because USB PD supports an output power of up to 100 watts, it can be used to charge a wide variety of battery-powered electronics. This benefits consumers in particular, who only need one lightning-fast charger for their laptops, tablet, smartphones and other devices.
Opportunities and challenges for USB PD
While USB power delivery offers many pluses, designers face some hurdles in creating top USB PD designs. Most crucially, USB power delivery protocol requires significantly higher power levels. At the same time, consumers prefer chargers and adapters with a small form factor. Thus designers must find the right semiconductor solutions to accommodate high power density and also appropriately address thermal management and potential EMI issues. Despite large production volumes, consumers need peace of mind that their charger works reliably. As a consumer good, performance must also be finely balanced with overall system cost.
