Product details
Overview
CYPD7271-68LQXQ from Infineon is a dual-port USB-C Power Delivery (PD) and buck-boost DC-DC controller IC with integrated Arm® Cortex®-M0 MCU, 128-KB flash, and two fully programmable 5.5–24 V input / 3.3–21.5 V output buck-boost controllers. It supports USB PD 3.2 with PPS, QC4+, AFC, and BC v1.2 protocols, and delivers hardware-based VBUS OVP/OCP/UVP/SCP protection for multi-port consumer chargers.
For engineers reviewing the CYPD7271-68LQXQ datasheet, CYPD7271-68LQXQ pinout, CYPD7271-68LQXQ application, or CYPD7271-68LQXQ equivalent, this device serves as a system-level PD controller with on-chip firmware programmability, dual-channel EMI-optimized switching control, and real-time thermal/current monitoring via integrated ADC and GPIOs - critical for compact, high-density AC-DC adapter designs.
Technical Context
The CYPD7271-68LQXQ implements two independent USB PD PHYs with BMC encoding/decoding, CC line slew rate control, and VCONN power switching per port. Its dual buck-boost subsystems operate in buck, boost, and two buck-boost regions with cycle-by-cycle current sensing, zero-crossing detection, and programmable phase shift to minimize input ripple.
MCU subsystem runs at 48 MHz with 16-KB SRAM and 32-KB ROM containing boot code and USB PD stack; peripherals include four SCBs (I²C/SPI/UART/LIN), three 8-bit ADCs, four 16-bit TCPWMs, and 19 GPIOs - enabling custom load sharing, thermistor-based temperature management, and dynamic VBUS regulation without external microcontroller.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port USB-C PD controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STUSB4760QTR | Single-port PD controller with external DC-DC control; no integrated buck-boost or MCU; relies on host MCU for PPS and protocol handling | Limited to single-port designs; requires external power stage and firmware development for multi-port coordination | Choose when cost sensitivity outweighs integration needs and design team has MCU firmware bandwidth |
| RAA489106GPGL | Dual-port PD controller with integrated buck-boost but fixed-function firmware; 64 KB flash, no user-programmable Cortex-M0 core | Suitable for standardized charger topologies only; lacks runtime customization for proprietary load-sharing or thermal algorithms | Prefer for high-volume, unchanging designs where field firmware updates and custom feature extension are unnecessary |
Compared with STUSB4760QTR and RAA489106GPGL, CYPD7271-68LQXQ uniquely combines dual-channel hardware PD PHYs, two fully programmable buck-boost controllers, and a user-accessible 128-KB flash Cortex-M0 - enabling differentiated features like adaptive phase shifting, dynamic PPS tuning, and closed-loop thermal derating without external components.

FAQ
What USB PD specifications does CYPD7271-68LQXQ support?
CYPD7271-68LQXQ fully complies with USB PD 3.2 specification, including Programmable Power Supply (PPS) mode with 20-mV voltage steps and 50-mA current steps, Extended Data Messaging (EDM), and Fast Role Swap. It also supports legacy protocols such as QC4+, Samsung AFC, Apple 2.4A, and BC v1.2 through dedicated hardware blocks - all without MCU overhead.
Does CYPD7271-68LQXQ require an external crystal oscillator?
No. CYPD7271-68LQXQ integrates a precision internal main oscillator (IMO) that eliminates the need for an external crystal or clock source. The IMO provides stable 48-MHz clocking for the Cortex-M0 core and USB PD PHY timing, meeting USB specification jitter requirements without added BOM cost or layout complexity.
How is overvoltage protection implemented on the VBUS line?
VBUS overvoltage protection is implemented via an on-die comparator with 24-V threshold and <1 µs response time. When VBUS exceeds the threshold, the device immediately disables the VBUS NFET gate driver and activates internal discharge paths for both VBUS_IN and VBUS_C nodes. This hardware-level action operates independently of firmware execution, ensuring fail-safe behavior during transient surges.
Can CYPD7271-68LQXQ support simultaneous PPS on both ports?
Yes. Each port has independent buck-boost controllers with dedicated PPS regulation loops, error amplifiers, and PWM modulators. Firmware can configure distinct PPS profiles per port - for example, Port 0 delivering 15 V @ 3 A (45 W) with ±20 mV tolerance while Port 1 delivers 9 V @ 2.22 A (20 W) with independent current limiting - all managed concurrently by the on-chip Cortex-M0.
