Evaluation Kit for Replacing Barrel Connectors with USB-Type C ConnectorsAugust 08, 2019 by Paul Shepard
The CY4533 EZ-PD™ Barrel Connector Replacement (BCR) Evaluation Kit (EVK) is based on the BCR product in Cypress' USB Type-C and Power Delivery controllers. This EVK is intended to be an evaluation vehicle for applications that would want to consume power over a USB Type-C Connector.
A device, such as a speaker, shaver, power tools, modem etc. that use a barrel connector for power will benefit from using a universal power interface such as USB Type-C. To make the transition easier, the CY4533 EVK provides a USB Type-C receptacle to consume power from a charger and then supply it over a terminal block. A barrel connector can be attached to this block using wires to convert a barrel input to USB Type-C.
EZ-PD™ BCR is Cypress' highly-integrated USB Type-C port controller targeting electronic devices that have legacy barrel connectors (up to 100W) or USB micro-B connectors for power such as drones, smart speakers, power tools, and other rechargeable devices.
EZ-PD BCR complies with the latest USB Type-C and USB Power Delivery (PD) standards and enables users to quickly convert their devices from being powered through a barrel connector to being powered via the USB-C connector with few external components and no firmware development is required.
EZ-PD BCR integrates a complete USB Type-C transceiver, USB PD policy manager, a load switch controller with a soft start, all termination resistors required for a USB Type-C port, and system-level ESD protection. It is available in a 24-pin QFN package.
