USB PD controller based on the USB PD specs

Renesas Electronics has announced its new Universal Serial Bus (USB) Power Delivery (PD) controller (part number µPD720250) that is based on the USB PD Specification to deliver up to 100W (5 A at 20 V) power over a USB PD cable.

Key features of the new USB PD controller as explained by Renesas:

(1) Based on the USB PD Specification
The µPD720250 USB PD controller is based on the USB PD Specification and in addition to supporting both the power supply and the power receiving sides of a USB connection, can flexibly support either role depending on the actual conditions of operation.
(2) Provision of optimal solutions for all types of system
The µPD720250 device is capable of control over an SMBus and can be easily incorporated into tablets and notebook PCs. It also provides flexible support for external ROM firmware and can thus implement optimal systems for both the power supply and power receiving sides. Furthermore, Renesas plans to provide powerful support for system development by offering solution kits that include both boards and software for all types of system.
(3) Low-power consumption to support Energy Star and the EuP Directive
The µPD720250 device takes advantage of Renesas' low-power technologies for reductions of both standby and operating power consumption and is appropriate for the Energy Star and the EuP Directive.
(4) Built-in regulator and compact package
The µPD720250 device includes an integrated 1.0 V regulator and can operate from a single 3.3 V power supply. It is provided in a compact package and enables lower costs and miniaturization in system construction.

Samples of Renesas Electronics' µPD720250 is expected to be available in July 2014.
