Product details
Overview
CYPAS212A132LQXQTXUMA1 from Infineon is an integrated secondary-side USB PD 3.1 controller with Active Clamp Flyback (ACF) and synchronous rectifier (SR) PWM control, supporting up to 28 V VBUS in Extended Power Range (EPR) mode, 300 kHz switching frequency, and CrCM/DCM/CCM/valley switching operation. It targets high-efficiency USB-C AC-DC adapters implementing dual-role charging protocols including QC5.0, PPS, Samsung AFC, and Apple Charging.
For engineers reviewing the CYPAS212A132LQXQTXUMA1 datasheet, CYPAS212A132LQXQTXUMA1 pinout, CYPAS212A132LQXQTXUMA1 application, or CYPAS212A132LQXQTXUMA1 equivalent, key selection criteria include secondary-side ACF timing accuracy, SR gate drive capability for logic-level MOSFETs, integrated LSCSA and dual VBUS discharge FETs, MCU-based protocol stack flexibility, and thermal robustness across –40°C to +150°C junction range.
Technical Context
The device implements a dual-loop control architecture: one error amplifier regulates constant voltage via FB/EА_OUT with external compensation, while a second handles constant current using LSCSA output and CC_COMP_GPIOx compensation. The 32-bit Cortex-M0+ core executes USB PD 3.1 stack with EPR support and manages multi-protocol negotiation (PD 2.0/3.0/3.1, QC2–5, AFC, BC1.2).
ACF and PWM signals share a single pulse-edge transformer via time-division multiplexing (TDM), decoded by companion primary controller CYPAP212. SR control supports ZCD and peak-detect sensing (via SR_CAP for >4 MHz resonance), with gate drive configurable to VDDD or 2×VDDD using internal doubler circuit across SR_CPP/SR_CPN.

Pinout & Package
32-pin QFN package (5 mm × 5 mm, 0.5 mm pitch) with exposed thermal pad; designed for high-power-density USB-C adapter PCB layouts requiring low-inductance SR and ACF signal routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBUS_IN | High-voltage input supply rail | Accepts 3.3–30 V input to power internal HV regulator; feeds bias for VBUS discharge FETs and LSCSA |
| SR_GDRV | Synchronous rectifier gate driver output | Drives external NFET gate; supports 1× or 2×VDDD drive strength depending on SR_CPP/SR_CPN capacitor configuration |
| SR_SEN | SR drain voltage sense input | Monitors external NFET drain node via resistive divider for ZCD and conduction timing; enables valley switching |

Equivalent & Alternatives
The following parts are listed as comparable options for similar secondary-side USB PD + ACF controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4282-AEC1 from Monolithic Power Systems | Single-function ACF controller without integrated PD stack or MCU; requires external microcontroller for PD protocol handling | Targeted at cost-sensitive automotive-grade ACF designs where USB PD is not required | Select when PD functionality is unnecessary and BOM cost is prioritized over integration |
| CYPD3177-40LQXQ from Infineon | USB PD 3.0 controller only; lacks ACF/PWM/SR integration - requires external flyback controller and SR driver | Used in legacy USB-C adapters with conventional QR flyback topology, no EPR or ACF support | Select only for non-ACF, lower-power (<65 W) designs where EPR and advanced SR modes are not needed |
Compared with MPQ4282-AEC1 and CYPD3177-40LQXQ, CYPAS212A132LQXQTXUMA1 uniquely integrates ACF timing, SR control, and full USB PD 3.1+EPR stack in one die - eliminating inter-chip timing skew, reducing PCB area by >25%, and enabling faster time-to-market for next-gen EPR adapters.

FAQ
What is the maximum supported VBUS output voltage in EPR mode?
CYPAS212A132LQXQTXUMA1 supports USB PD Extended Power Range up to 28 V VBUS output, compliant with USB PD 3.1 specification Annex A. This is achieved through firmware-configurable OVP threshold and reinforced isolation design validated per IEC 62368-1 for 28 V operation.
Does it require an external microcontroller to implement USB PD?
No. The integrated 32-bit ARM Cortex-M0+ core with 64 KB Flash and 64 KB ROM hosts a field-upgradable USB PD 3.1 stack including EPR, PPS, and multi-protocol support - no external MCU is required for full PD functionality.
How does the SR gate driver support both standard and logic-level MOSFETs?
The SR_GDRV output can be configured to drive at either VDDD (3.0–5.5 V) or 2×VDDD using an internal charge pump powered by the SR_CPP/SR_CPN capacitor pair. This provides sufficient gate voltage for logic-level NFETs (2.5 V threshold) and ensures strong turn-on for standard NFETs (4 V threshold) without external boost circuitry.
Can it operate with active clamp flyback topologies using GaN primary switches?
Yes. CYPAS212A132LQXQTXUMA1 is explicitly designed for ACF flyback systems with GaN or SiC primary-side switches. Its TDM-based PWM/ACF signal transmission and precise timing control ensure reliable synchronization with high-speed primary-side gate drivers like Infineon's CoolGaN™ ICE5 series.
