TI claims the industry’s first 200-W and 100-W USB Type-C and USB Power Delivery (PD) controllers

By Gina Roos, editor-in-chief

With fully integrated power paths, the new USB Type-C and USB Power
Delivery (PD) controllers from Texas Instruments (TI) deliver smaller solution
sizes and cost savings by reducing the number of external components required
for computing applications. Claiming the industry’s first 200-W and 100-W USB
Type-C and USB Power Delivery (PD) controllers, the TPS65987D
and TPS65988 devices support computing applications, as well as a
variety of other end products including cordless power tools, gaming, and
virtual reality headsets.

The single-port TPS65987D, designed to source 100 W of power,
integrates independent 20-V, 5-A source and sink load switches. Key features
include a low RDS(on) (25
mΩ) for efficient charging and reverse current protection to protect the system
and controller from overcurrent.

The dual-port TPS65988, which sources 200 W of power, provides two
integrated 5-A bidirectional load switches and external power-path control to
enable simultaneous 5-A source capability, said TI. The 200 W of power allows
for fast USB Type-C charging while maintaining low RDS(on), and the two integrated
5-A FET paths enable high-power applications, including PC notebooks, docking
stations, and connected peripherals.

The devices are USB PD 3.0-certified, UL-recognized, and
International Electrotechnical Commission (IEC) safety-certified. The devices
are pre-programmed to support several popular use cases including DisplayPort
and Thunderbolt applications.

Reference designs are available: Power Duo Source 200 W
and Power Duo Sink 200 W USB-C PD. Other resources include

TPS65987D and TPS65988,
available in 7 × 7-mm split-pad, quad flat no-lead (QFN) packaging, are
priced at $1.99 and $2.99, respectively, in quantities of 1,000.
The devices are available from the TI store and TI’s authorized distributors.
