Infineon’s EZ-PD™ Barrel Connector Replacement (BCR) is a highly integrated USB Type-C port controller that enables users to quickly convert their devices from being powered via barrel connector or USB micro-B to via USB-C connector, with few external components. The EZ-PD™ BCR complies with the latest USB Type-C and USB power delivery (PD) standards, and no firmware development is required. The device supports Apple charging at 2.4 A in addition to BC 1.2, QC 2.0, and AFC standards.
Infineon produces the CY4535 EZ-PD™ BCR LITE Evaluation Kit and the CY4534 EZ-PD™ BCR PLUS Evaluation Kit for this technology, each a reference design for replacing an existing barrel power connector with a USB Type-C™ connector.
The LITE kit is based on the CYPD3178 EZ-PD BCR USB Type-C Port Controller, which does not support the USB-PD protocol, unlike the CYPD3177 or CYPD3176 devices – If you require this capability, consider the PLUS kit, though this necessitates use of the CY4500 EZ-PD Protocol Analyzer (not included) to observe and analyse the USB power delivery packets exchanged between the evaluation kit and the USB Type-C power adapter.
The CYPD3178 device of the LITE option can be used for USB-C sink or devices that are only capable of accepting power from the following: USB Type-C only chargers that are capable of delivering 5 V (up to 3 A), or USB Type-A or Type-C chargers that can operate at 5 V, 9 V, 12 V, 15 V, or 20 V using proprietary methods of negotiation over the D+/D- lines. The PLUS option additionally supports power delivery 3.0.
These evaluation kits ship with pre-programmed firmware, which can be customized using the EZ-PD™ Configuration Utility, and there are several features throughout the board to protect end devices during testing. Please specify which kit you require in your application.
