IFXCYPD7271-68LQXQ

Overview

The CYPD7271-68LQXQ is a highly integrated EZ-PD CCG7D dual-port USB-C Power Delivery controller designed specifically for multi-port chargers and power adapters. It combines an ARM Cortex-M0 processor with integrated buck-boost controllers, VBUS NFET gate drivers, and hardware-based protection to reduce component count in high-density power designs. The device supports USB-PD 3.0 with Programmable Power Supply (PPS) and various legacy charging protocols.

Why Choose This Part

This controller minimizes BOM cost by integrating the buck-boost PWM controller, VCONN power supply, and current sense amplifiers directly into the 68-QFN package. It features programmable phase shifting across the two ports to significantly reduce EMI, and the 128KB of flash memory allows for field-upgradable firmware to maintain compatibility with evolving USB-C standards.

Applications

Getting Started

Designers should utilize the Infineon EZ-PD Configuration Utility to customize PD profiles and firmware parameters without extensive coding. Hardware evaluation can be performed using the CY4534 EZ-PD CCG7D Evaluation Kit, and firmware development is supported through the ModusToolbox software environment.

Also Consider

STUSB4500 STMicroelectronics - Consider if you need a standalone sink-only controller that does not require an external microcontroller for PD negotiation.

TPS25750 TITexas Instruments - An alternative highly integrated USB-PD controller with an internal power path and easy I2C configuration for power-only applications.
