Product details

Overview

CYPD717140LQXQTXUMA1 from Infineon is a single-port USB Type-C Power Delivery (PD) 3.1 controller with integrated buck-boost regulator, Arm® Cortex®-M0 MCU (48 MHz, 128 KB flash), 4.5–24 V input (40 V tolerant), 3.3–21.5 V output, and support for Programmable Power Supply (PPS) at 20-mV/50-mA steps - deployed in consumer wall adapters and cigarette lighter chargers.

For engineers reviewing the CYPD717140LQXQTXUMA1 datasheet, CYPD717140LQXQTXUMA1 pinout, CYPD717140LQXQTXUMA1 application, or CYPD717140LQXQTXUMA1 equivalent, key selection criteria include PD 3.1 + PPS compliance, integrated buck-boost switching (150–600 kHz), hardware-based VBUS OVP/OCP/UVP/SCP protection, CC logic with Rp/Rd configuration, and on-chip VCONN (100 mW) sourcing capability.

Technical Context

The device implements a full USB PD 3.1 PHY with BMC encoding/decoding, collision avoidance, and extended messaging (up to 260 bytes via chunking), paired with configurable Rp/Rd termination and VBUS provider NFET gate driver. It integrates dual-mode buck-boost control with slope compensation, zero-crossing detection, and selectable PSM/FCCM operation.

Analog subsystem includes two 8-bit ADCs (supporting internal temperature sensing and external thermistor inputs), high-voltage current sense amplifier for VBUS (5 mΩ shunt), and dedicated error amplifiers for CV/CC regulation. Digital resources comprise three SCBs (I²C/SPI/UART/LIN), eight TCPWMs, cryptographic TRNG, and 13 GPIOs - two of which are HV-tolerant for overvoltage monitoring.

Equivalent & Alternatives

The following parts are listed as comparable options for similar USB PD + buck-boost controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CYPD727140LQXQTXUMA1	Same CCG7SC family with identical MCU, PD 3.1, and buck-boost architecture; differs only in factory-programmed firmware variant (e.g., default policy, VID/PID)	Drop-in replacement where OEM-specific USB identifiers or preloaded policy tables are required	Select when certified USB-IF TID or vendor-defined device descriptors are mandatory
STUSB4500QTR	Dedicated PD controller only - no integrated buck-boost; requires external DC-DC stage and separate MCU for PPS or custom logic	Suitable for designs already using discrete buck-boost ICs and separate microcontrollers	Choose only if existing power stage architecture prevents integration or if lower BOM cost outweighs footprint/complexity gains

Compared with CYPD717140LQXQTXUMA1, the CYPD7271 variant offers identical silicon functionality with differentiated firmware, while STUSB4500QTR provides basic PD control but shifts buck-boost implementation, protection logic, and system management to external components - increasing design effort and board area.

FAQ

What is the maximum supported USB PD output power with CYPD717140LQXQTXUMA1?

The device itself does not impose a fixed power limit; output power depends on external component selection (MOSFETs, inductors, thermal design) and firmware configuration. With appropriate 24 V input and 21.5 V/5 A PPS output, it supports up to ~100 W in continuous operation under industrial temperature conditions and proper heatsinking.

Does CYPD717140LQXQTXUMA1 require an external crystal or oscillator?

No. The device integrates a precision internal oscillator that meets USB PD timing requirements, eliminating the need for an external crystal or clock source. This reduces BOM cost and PCB area while maintaining ±1.5% frequency accuracy across temperature and voltage.

Can the buck-boost controller operate in buck-only or boost-only mode?

Yes. Firmware can configure the controller to operate exclusively in buck mode (for VIN > VOUT), boost mode (for VIN < VOUT), or automatic buck-boost mode (for wide-input applications). Mode selection is dynamic and supports seamless transitions during PPS voltage adjustments.

How is firmware updated in the field for CYPD717140LQXQTXUMA1?

Firmware updates are performed via SWD (Serial Wire Debug) interface using Infineon's ModusToolbox™ and EZ-PD™ Configuration Utility. Field updates preserve customer data in reserved flash sectors and support secure signature verification to prevent unauthorized code execution.
