Controllers increase power in USB dual- and single port applications

Claimed to be the first 200 and 100W USB Type-C and USB Power Delivery controllers with fully integrated power paths, the TPS65987D and TPS65988 can simplify designs, claims Texas Instruments.

The two USB Type-C and USB Power Delivery (PD) controllers offer system designers the industry’s highest level of integration which can reduce design complexity and overall cost, claims Texas Instruments.

The devices are the industry’s first USB PD controllers to source 100 and 200W of power, respectively, to support computing applications and enable the benefits of USB Type-C in applications such as virtual reality headsets, gaming and cordless power tools.

The single-port TPS65987D, is designed to source 100W of power. The controller integrates independent 20V, 5.0A source and sink load switches. Low RDS (on)  (25mOhm) and reverse current protection in the TPS65987D manage a port’s charging needs.

The dual-port TPS65988 can source 200W of power, and offers two integrated 5.0A bi-directional load switches and external power-path control to enable simultaneous 5.0A source capability.

The devices are USB PD 3.0-certified, UL-recognised, and International Electrotechnical Commission (IEC) safety-certified. They are pre-programmed to support several of the most common use cases including DisplayPort and Thunderbolt applications. A configuration tool is available to support additional use cases.

Integrated USB PD controllers can help designers reduce design complexity, compared to discrete implementations which typically require 18 external power-path components, explains Texas Instruments. The controllers offer integrated reverse current protection for multiple power paths, to further save board space and protect the system and controller from over-current.

The 200W allows fast USB Type-C charging, with two integrated 5.0A field-effect transistor (FET) paths to enable high-power applications such as PC notebooks, docking stations or connected peripherals while maintaining low RDS (on) for efficient charging with minimal power loss.

Both devices are available now in 7.0 x 7.0mm split-pad, quad flat no-lead (QFN) packaging.
