Product details
Overview
XDPL8218XUMA1 from Infineon is a digital single-stage flyback controller with integrated Power Factor Correction (PFC), Secondary Side Regulation (SSR), and constant voltage (CV) output. It supports universal AC input (90–305 Vrms), delivers >0.98 power factor and <10% THD at 33–100% load, and achieves >90% typical efficiency in QRM1/DCM modes for LED driver front-stage applications.
For engineers reviewing the XDPL8218XUMA1 datasheet, XDPL8218XUMA1 pinout, XDPL8218XUMA1 application, or XDPL8218XUMA1 equivalent, this controller enables rapid configuration of protection thresholds, operation mode transitions (QRM1/DCM/ABM), and PFC compensation via UART-critical for Class 2 LED driver design with <100 mW standby power and industrial qualification per JEDEC47/20/22.
Technical Context
The XDPL8218XUMA1 implements a digitally controlled multimode flyback architecture with line-synchronized zero-crossing detection (ZCD) and dual-path voltage estimation (input via HV pin, output via FB pin). Its digital core executes real-time PFC correction to mitigate input capacitance effects on harmonic distortion while maintaining smooth transitions between Quasi-Resonant Mode 1 (QRM1), Discontinuous Conduction Mode (DCM), and Active Burst Mode (ABM).
Protection logic is fully configurable via UART: brown-in/brown-out response (auto-restart or latch), output overvoltage/undervoltage thresholds, VCC OVP/UVP, and primary MOSFET overcurrent detection via CS pin. The internal 600 V startup cell on the HV pin enables direct high-voltage charging of VCC during startup without auxiliary winding.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 90–305 Vrms AC or DC: Enables global mains compatibility and DC-powered industrial lighting systems. |
| Power Factor (PF) | >0.98 at ≥33% load: Meets IEC 61000-3-2 Class C requirements for LED drivers without external PFC stage. |
| Total Harmonic Distortion (THD) | <10% at ≤277 Vrms: Reduces harmonic current injection into AC grid, easing EMI filter design. |
| Efficiency | >90% typical: Achieved via valley-switching (QRM1) at high load and frequency-controlled DCM at medium load. |
| Standby Power | <100 mW (no-load): Complies with Energy Star and EU CoC Tier 2 requirements using Active Burst Mode. |
| Operating Modes | QRM1, DCM, ABM: Digitally selected based on filtered FB voltage; enables optimal trade-off between efficiency, noise, and regulation. |
| Protection Configuration | UART-programmable thresholds and reactions (auto-restart/latch) for OVP, UVP, OCP, and thermal events. |
Pinout & Package
XDPL8218XUMA1 is housed in a PG-DSO-8 (150-mil) package with exposed thermal pad for enhanced power dissipation in compact LED driver designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ZCD | Zero-Crossing Detection Input | Connects to transformer auxiliary winding; enables line synchronization, input voltage estimation, and SSR output sensing. |
| FB | Secondary-Side Feedback Input | Digitally samples and filters output voltage for SSR CV regulation; sampling rate adapts to AC line or DC input. |
| CS | Current Sense Input | Monitors primary-side MOSFET current via shunt resistor for peak-current-mode control and overcurrent protection. |
| GD | Gate Driver Output | Drives external CoolMOS™ P7 MOSFET gate; slope configurable to optimize switching loss and EMI. |
| HV | High-Voltage Startup Input | Internally charges VCC via 600 V startup cell; provides line sync signal and input voltage estimation path. |
| UART | Configuration Interface I/O | Serial interface for programming protection thresholds, mode transition points, and PFC parameters post-manufacture. |
| VCC | Supply Voltage Input/Sense | Regulated IC supply (typically 12–20 V); includes UVLO and OVP for robust start-up and fault handling. |
| GND | Signal Ground Reference | Common return for analog sensing (FB, ZCD, CS), digital logic, and gate drive return path. |
Key Features
| Feature | Design Value |
|---|---|
| Enhanced Digital PFC | Compensates input capacitance effect on PF/THD in real time, enabling single-stage compliance without bulk capacitor derating. |
| Configurable Multimode Control | QRM1, DCM, and ABM dynamically selected by filtered FB voltage-no external components needed for mode transitions. |
| Active Burst Mode (ABM) | Reduces audible noise and standby power to <100 mW by gating burst pulses with precise wake-up timing (nwakeup parameter). |
| Digital Protection Tuning | All protections (OVP, UVP, OCP, thermal) have user-defined thresholds and auto-restart/latch behavior via UART GUI. |
| Industrial Qualification | Qualified per JEDEC47/20/22 for temperature cycling, humidity, and HTOL-validated for 10+ year LED driver field life. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital flyback controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UCC28056DR | Analog PFC + flyback combo; no digital configurability, fixed protection thresholds, no UART interface. | Lacks SSR CV precision and ABM noise control; requires external components for THD optimization. | Choose for cost-sensitive, low-volume designs where firmware flexibility and Class 2 compliance are not required. |
| ICE5QRSD20AG | Quasi-resonant flyback controller with analog PFC; no digital PFC correction or UART tuning capability. | Higher THD (>15%) above 264 Vrms; limited brown-out response options (fixed latch-only). | Prefer when legacy analog design reuse is prioritized over PF/THD margin and programmable protection. |
Compared with UCC28056DR and ICE5QRSD20AG, XDPL8218XUMA1 uniquely integrates digital PFC correction, UART-based parameter tuning, and ABM with <100 mW standby-enabling single-stage Class 2 LED drivers that meet stringent global energy and harmonic standards without design iteration.

FAQ
Is XDPL8218XUMA1 pin-compatible with earlier XDPL82xx variants?
No. XDPL8218XUMA1 uses PG-DSO-8 with specific pin assignments (e.g., UART on Pin 6, HV on Pin 5) and requires firmware version 0.1.1.7. Earlier variants like XDPL8211 use different pinouts and lack UART configuration capability-hardware redesign is required for migration.
What external components are mandatory for basic operation?
Mandatory components include: ZCD resistive divider (for line sync and voltage sensing), FB voltage divider (to scale output to 2.428 V reference), CS shunt resistor (for current sensing), GD series gate resistor (to control slew rate), and HV startup resistor (to limit current into 600 V cell). No optocoupler or TL431 is needed for SSR.
How is the UART interface used in production?
The UART interface connects to Infineon's XDP GUI via USB-to-UART adapter. Engineers configure protection thresholds, mode transition voltages, PFC gain, and ABM parameters before final test. Configuration is stored in on-chip nonvolatile memory and persists through power cycles-no external EEPROM required.
Does XDPL8218XUMA1 support DC input operation?
Yes. When AC line sync is unavailable (e.g., DC input), the controller defaults to 64-sample-per-9.823-ms FB sampling and uses HV/ZCD pins for input voltage estimation. All protections-including brown-in/out, OVP, and thermal-remain fully functional with identical thresholds and reactions.
