Product details
Overview
CYPAS212A132LQXQXQLA1 from Infineon Technologies 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-mode charging protocols including QC5.0, PPS, and Samsung AFC.
For engineers reviewing the CYPAS212A132LQXQXQLA1 datasheet, CYPAS212A132LQXQXQLA1 pinout, CYPAS212A132LQXQXQLA1 application, or CYPAS212A132LQXQXQLA1 equivalent, key selection criteria include secondary-side ACF timing accuracy, SR gate drive voltage doubling capability, integrated LSCSA for CC regulation, dual CC-line protocol engine compliance, 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 PWM generator uses programmable ramp feedforward and time-division multiplexing (TDM) to share a single pulse-edge transformer for both PWM and ACF signals.
Its MCU subsystem integrates a 32-bit Cortex-M0+ (64 KB Flash, 8 KB SRAM, 64 KB ROM) executing protocol stack and protection logic, enabling dynamic negotiation of PD contracts, EPR transitions, and multi-protocol fallback-all without external microcontroller intervention.

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 | Automotive-grade AEC-Q100 qualified; lacks integrated MCU and PD protocol engine-requires external microcontroller for PD negotiation. | Targeted at automotive USB-C outlets where functional safety (ASIL-B) is mandatory; not suitable for consumer EPR adapters. | Select when ISO 26262 compliance and extended temperature operation (–40°C to +125°C ambient) outweigh need for integrated PD stack. |
| STCH03 from STMicroelectronics | Standalone SR controller only; no ACF, no PD, no MCU-relies on primary-side controller for all timing and protocol functions. | Used in cost-sensitive, non-EPR USB-C adapters where PD negotiation occurs externally and ACF is not implemented. | Select only if design already uses a PD-capable primary controller (e.g., STCH02) and requires minimal secondary-side overhead. |
Compared with MPQ4282-AEC1 and STCH03, CYPAS212A132LQXQXQLA1 uniquely integrates PD 3.1 EPR protocol handling, ACF timing generation, and SR control in one die-reducing system latency, eliminating inter-controller communication, and enabling faster transient response during voltage step changes.

FAQ
What is the maximum VBUS output voltage supported by CYPAS212A132LQXQXQLA1 in EPR mode?
CYPAS212A132LQXQXQLA1 supports up to 28 V VBUS output in USB PD Extended Power Range (EPR) mode, compliant with USB PD 3.1 specification. This enables 240 W power delivery (28 V × 8.6 A) and is enforced by hardware-limited OVP threshold and protocol-layer contract validation within the integrated Cortex-M0+ firmware.
Does CYPAS212A132LQXQXQLA1 require an external microcontroller to implement USB PD communication?
No. CYPAS212A132LQXQXQLA1 integrates a full USB PD 3.1 protocol stack executed on its embedded 32-bit Cortex-M0+ core with 64 KB Flash and 64 KB ROM. All BMC encoding/decoding, policy engine execution, and EPR state machine handling occur autonomously-no external MCU is needed for basic or advanced PD functionality.
How does the SR gate driver support both standard and logic-level MOSFETs?
The SR_GDRV pin delivers gate drive voltage either at VDDD (3.0–5.5 V) or doubled to 2×VDDD using an internal charge pump circuit. The doubler is enabled by connecting a capacitor between SR_CPP and SR_CPN pins. This allows driving standard MOSFETs requiring ≥10 V VGS or logic-level devices needing only 4.5 V, without external level shifters.
Can CYPAS212A132LQXQXQLA1 operate in discontinuous conduction mode (DCM) and continuous conduction mode (CCM) simultaneously?
No-it operates in one conduction mode per design configuration, selected via firmware configuration and external component tuning. However, it supports automatic mode transitions: e.g., DCM at light load, CrCM at medium load, and CCM at heavy load-enabled by real-time ZCD and peak-detect sensing on SR_SEN and SR_CAP pins.
