Product details
Overview
CYPET131XQMA1 from Infineon Technologies is a pulse edge transformer (PET) designed for isolated PWM signal transmission between PAG1P (primary-side controller) and PAG1S (secondary-side controller) in USB Power Delivery AC/DC adapters, with 1:3 turns ratio, 15.66 µH ±35% primary inductance at 100 kHz/0.3 V, 3.0 kV AC hi-pot isolation, and T6×4×2.15 mm core geometry.
For engineers reviewing the CYPET131XQMA1 datasheet, CYPET131XQMA1 pinout, CYPET131XQMA1 application, or CYPET131XQMA1 equivalent, key selection criteria include turns ratio matching for PAG1P-PAG1S synchronization, hi-pot rating for reinforced isolation compliance, inductance tolerance impact on timing fidelity, and thermal class compatibility with adapter PCB layout constraints.
Technical Context
The CYPET131XQMA1 implements a fixed-ratio (1:3) pulse edge coupling architecture to transmit fast-rise-time PWM edges across galvanic isolation barriers in USB PD power adapters. It operates without DC bias or continuous current handling-only transient edge energy transfer is supported.
Its winding configuration supports unidirectional signal flow from secondary-side PAG1S to primary-side PAG1P, enabling precise timing synchronization during steady-state operation after startup. The device requires no external biasing or termination and functions solely as a passive magnetic coupler.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Turns Ratio | 1:3 - sets voltage scaling for PWM edge detection threshold alignment between PAG1S output and PAG1P input |
| Primary Inductance | 15.66 µH ±35% @ 100 kHz/0.3 V - defines low-frequency impedance and edge-shaping response time |
| Hi-Pot Isolation | 3.0 kV AC, 50/60 Hz, 4 mA leakage - meets reinforced insulation requirements for Class II AC/DC adapters |
| Core Geometry | T6 × 4 × 2.15 mm - enables compact placement near PAG1P/PAG1S ICs with minimal board area footprint |
| Insulation System | Phenolic base (UL E41429), TEX-E insulated wire (UL E206440/E357999), silicone coating (200°C) - ensures long-term reliability under thermal cycling |
| RoHS Compliance | Yes - supports lead-free reflow assembly and environmental compliance for global markets |
Pinout & Package
Package: Surface-mount pulse edge transformer with T6×4×2.15 mm ferrite core, phenolic base, and 4-terminal configuration (2 primary + 2 secondary pins). No exposed leads; terminals are solder pads on underside.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Primary) | Primary winding start | Connects to PAG1S PWM output driver node; referenced to SR_VSS ground |
| 2 (Primary) | Primary winding finish | Connects to PAG1S GND return path; completes primary loop for edge coupling |
| 3 (Secondary) | Secondary winding start | Feeds scaled PWM edge to PAG1P PULSEIN pin; polarity determines edge detection direction |
| 4 (Secondary) | Secondary winding finish | Connects to PAG1P BGND; establishes reference for isolated secondary-side signal domain |
Key Features
| Feature | Design Value |
|---|---|
| Fixed 1:3 Turns Ratio | Enables direct interface with PAG1S output drive strength and PAG1P input sensitivity without external level-shifting components |
| 3.0 kV AC Reinforced Isolation | Meets IEC 62368-1 creepage/clearance requirements for 230 VAC input adapters without additional isolation barriers |
| 15.66 µH Primary Inductance | Optimized to preserve PWM edge rise/fall times (<100 ns) while suppressing high-frequency ringing in typical adapter layouts |
| T6×4×2.15 mm SMT Footprint | Allows placement within 5 mm of PAG1P/PAG1S QFN packages, minimizing parasitic inductance in critical signal paths |

FAQ
What is the maximum recommended operating frequency for CYPET131XQMA1?
The CYPET131XQMA1 is characterized for use with PAG1P-PAG1S systems operating up to 650 kHz PWM frequency. Its 15.66 µH inductance and core material support clean edge transmission without excessive ringing or attenuation at this rate. Higher frequencies may degrade edge fidelity due to winding capacitance and core losses.
Can CYPET131XQMA1 be used with PAG2P-PAG2S controllers?
No. CYPET131XQMA1 has a fixed 1:3 turns ratio optimized for PAG1P-PAG1S timing synchronization. PAG2P-PAG2S requires the 1:2 ratio of CYPET121. Using CYPET131XQMA1 with PAG2x controllers causes mismatched voltage scaling at the PULSEIN input, leading to unreliable edge detection and potential regulation failure.
Is CYPET131XQMA1 compliant with UL 1577 or IEC 60747-5-2?
CYPET131XQMA1 meets IEC 62368-1 reinforced insulation requirements with its 3.0 kV AC hi-pot rating. It is not certified to UL 1577 (optocoupler standard) or IEC 60747-5-2 (opto-isolator safety standard), as it is a passive transformer-not an optocoupler-and falls under magnetic isolation evaluation per IEC 61558-2-16.
Does CYPET131XQMA1 require external biasing or termination resistors?
No. CYPET131XQMA1 operates passively as a pulse edge coupler and requires no DC bias, termination, or damping components. Its design relies on intrinsic winding impedance and core saturation characteristics to shape edges. Adding external resistors degrades signal integrity and violates the reference design validated in Infineon's PAG1P-PAG1S application notes.
