Cypress Introduces New Highly Integrated Controller to Simplify Design of Next-Generation USB-C Power Adapters and Chargers

Monday, August 6, 2018

Cypress Semiconductor Corporation (Nasdaq: CY), a leader in the USB-C market, today announced a new USB-C controller that supports Power Transfer (PD), which simplifies power adapters and mobile phone chargers. Car charger and mobile power supply design. The Cypress EZ-PDTM CCG3PA controller supports the PD 3.0 standard in conjunction with Programmable Power Supply (PPS) and Qualcomm Quick Charge (QC) 4.0 protocols, enabling new power product designs to deliver an optimized fast charging experience. As these technology standards and USB Type-C standards continue to evolve, compatibility and interoperability will be an ongoing challenge, and this programmable CCG3PA controller can be upgraded with firmware to keep pace with developments. Address interoperability issues. The controller's high level of integration significantly reduces bill of materials and simplifies design, replacing multiple discrete devices with a single-chip solution.

Ajay Srikrishna, vice president of Cypress's Wired Connections division, said: "With the popularity of USB-C applications this year, the demand for USB-C power will increase. This puts more pressure on our customers. Need to quickly bring power adapters, mobile phone chargers, car chargers and mobile power to the market while keeping up with the fast-growing USB standard. Our highly integrated EZ-PD CCG3PA controller is designed to simplify USB-C power products The requirements are optimized to support not only the required charging standards, but also to keep up with the development of technical standards through firmware upgrades."

The EZ-PD CCG3PA controller is a single-chip solution that integrates an error amplifier for constant voltage, constant current, and PPS applications, a 30 V regulator that allows VBus direct operation, and a VBus on the configuration channel (CC) pin. Short-circuit protection, gate drivers for high-voltage power FETs, low-side current-sense amplifiers, dedicated hardware for traditional charger detection protocols, and system-level electrostatic discharge (ESD) protection minimize material costs for USB-C power products. Programmable overvoltage and overcurrent circuits protect the system from power overload and other erroneous operations. It also integrates ARM® Cortex®-M0 and 64KB Flash for simultaneous firmware read and write. In addition, this product helps design an efficient USB-C power adapter for a wide range of applications, including mobile phones and personal computers.
