Product details
Overview
CYPD3172P-24LQXQ from Infineon Technologies (formerly Cypress) is a USB Type-C port controller with integrated NFET gate driver, compliant with USB PD 3.0 PPS, QC4.0, and BC1.2 standards. It implements dual error amplifiers for independent constant voltage (3.3–21 V) and constant current (1–3 A) regulation, integrates full BMC transceiver, CC line terminations, LSCSA (5–150 gain), and drives external load-switch NFET via VBUS_CTRL pin. Used in compact, high-efficiency AC/DC power adapters.
For engineers reviewing the CYPD3172P-24LQXQ datasheet, CYPD3172P-24LQXQ pinout, CYPD3172P-24LQXQ application, or CYPD3172P-24LQXQ equivalent, key selection criteria include its opto-coupled or direct secondary-side feedback capability, integrated 24-pin QFN package with –40 °C to +105 °C operation, and support for USB PD 3.0 Programmable Power Supply (PPS) with real-time CV/CC mode switching.
Technical Context
The device embeds a Cortex-M0 MCU subsystem (64 KB Flash, 4 KB SRAM) running proprietary USB-PD protocol stack, with hardware BMC PHY and collision-avoidance logic for half-duplex CC communication. Its analog regulation architecture uses two independent error amplifiers-one for CV (FB/EА_OUT) and one for CC (CC_COMP_GPIO2/EА_OUT)-each with internal reference (0.744 V) and programmable IDACs for precise output tuning.
Power management includes a high-voltage regulator (3.3–21.5 V input → 5 V or VBUS_IN − 300 mV output), dual LDOs (VDDD: 3.0–5.5 V; VCCD: 1.8 V), and configurable protection blocks (OVP/UVP/OCP/SCP/OTP). The NFET gate driver delivers VBUS_IN + 8 V clamp-limited output on VBUS_CTRL to control external high-side load switch.
Key Specifications

Pinout & Package
Package: 24-pin QFN (4 mm × 4 mm, 0.5 mm pitch), thermally enhanced with exposed EPAD connected to VSS.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VSS (Pins 2, 15) | Ground reference | Primary analog/digital ground return; EPAD must be soldered to PCB ground plane for thermal and EMI performance |
| CC1 / CC2 (Pins 14, 13) | USB PD Configuration Channel | BMC-encoded bidirectional communication lines; integrate Rp termination switches and 390-pF capacitor requirement per spec |
| VBUS_CTRL (Pin 19) | NFET gate driver output | Delivers clamped VBUS_IN + 8 V to drive external high-side NFET; eliminates need for discrete level shifter or charge pump |
| FB / EA_OUT (Pins 9, 8) | CV error amplifier interface | FB accepts 0.744 V reference; EA_OUT sources/sinks current proportional to CV error for opto-coupler or direct feedback |
| CC_COMP_GPIO2 (Pin 7) | CC error amplifier compensation | Provides compensation node for CC loop; also functions as GPIO P0.2 when CC mode not active |
| CSP / CSN (Pins 11, 10) | Current sense inputs | Differential inputs to integrated LSCSA; supports 5 mΩ sense resistor with offset cancellation for <±1% current measurement |
| DP_GPIO5 / DM_GPIO4 (Pins 17, 16) | Legacy charging interface | Implement BC1.2, QC, AFC, Apple detection without external components; reconfigurable as SWD or GPIO |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent error amplifiers | Separate CV and CC regulation paths enable simultaneous, decoupled control of output voltage and current per USB PD PPS requirements |
| Integrated BMC transceiver + Rp switches | Eliminates 4 external resistors and associated routing; reduces BOM count and layout complexity for CC line compliance |
| Configurable protection suite | OVP/UVP/OCP/SCP/OTP thresholds set via firmware; enables field-updatable safety margins without hardware change |
| Opto-coupler or direct feedback support | EA_OUT pin drives opto-LED directly or interfaces with secondary controller's FB pin-no external op-amp needed in either topology |
| 6 GPIOs with multiplexing | GPIO0/GPIO1/GPIO3 are dedicated; DP/DM/CC_COMP double as GPIOs-enables flexible feature expansion (e.g., temperature monitoring, LED status) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB Type-C port controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RAA489100GP#AA0 | Integrates primary-side flyback controller + secondary-side PD controller in single chip; no external MCU required | Targeted at cost-sensitive, low-component-count AC/DC designs; lacks independent CC/CV error amplifiers and opto-feedback flexibility | Select when BOM reduction outweighs need for PPS precision and secondary-side programmability |
| IP2721 | Standalone PD3.0 controller with integrated MOSFET drivers but no embedded MCU or firmware update capability | Requires external microcontroller for custom protocol extensions; limited to fixed PD profile sets without runtime IDAC tuning | Select for simple, fixed-profile adapters where firmware updates and adaptive CC/CV are unnecessary |

FAQ
What is the function of the EA_OUT and FB pins in CYPD3172P-24LQXQ?
EA_OUT is the output of the constant voltage (CV) error amplifier, sourcing or sinking current proportional to the difference between the FB pin voltage and the internal 0.744 V reference. FB serves as the negative input to the CV error amplifier and connects to an external resistor divider on the secondary side. Together, they enable opto-coupled or direct feedback control of the primary-side flyback controller without external op-amps or DACs.
Does CYPD3172P-24LQXQ support USB PD 3.0 Programmable Power Supply (PPS)?
Yes, CYPD3172P-24LQXQ fully supports USB PD 3.0 PPS with 20 mV voltage steps and 50 mA current steps. Its dual error amplifiers independently regulate constant voltage (3.3–21 V) and constant current (1–3 A), and internal IDACs adjust FB and CC_COMP nodes in real time to achieve precise PPS output control per negotiated profile.
Can CYPD3172P-24LQXQ operate without an opto-coupler?
Yes. The device supports both opto-coupled and direct feedback architectures. In direct mode, the FB pin connects to the secondary controller's feedback node, and internal IDACs source/sink current to adjust the voltage setpoint-eliminating the opto-isolator while retaining full PPS functionality and CV/CC regulation accuracy.
What protection features are configurable in firmware?
Overvoltage (OVP), undervoltage (UVP), overcurrent (OCP), short-circuit (SCP), and over-temperature (OTP) protection thresholds are all configurable via firmware. These settings can be updated in-field using the SWD interface or over the CC line, enabling safety margin adjustments and regional certification compliance without hardware revision.
