Product details
Overview
XDPL8210XUMA1 from Infineon is a digitally configurable single-stage flyback controller IC with integrated Power Factor Correction (PFC), primary-side regulated constant current (CC) output, and Limited Power (LP) mode. It supports universal AC input (90–305 Vrms), achieves ±2% line/load regulation, delivers PF up to 0.99 and THD < 10%, and enables dimming down to 1% with 60 mW standby power - deployed in Class 2-compliant LED drivers for industrial luminaires.
For engineers reviewing the XDPL8210XUMA1 datasheet, XDPL8210XUMA1 pinout, XDPL8210XUMA1 application, or XDPL8210XUMA1 equivalent, this controller's digital configurability (via UART), QRM1/DCM/ABM multimode operation, adaptive OVP, and PFC compensation are critical for LED driver BOM optimization, flicker-free dimming validation, and UL1310-compliant design verification.
Technical Context
The XDPL8210XUMA1 implements a digital control core with real-time estimation of input voltage (via HV pin), output voltage (via ZCD auxiliary winding), and output current (via CS shunt sensing), enabling primary-side regulation without optocouplers. Its PFC function actively compensates for input capacitance effects on harmonic distortion.
It operates across three modes: Quasi-Resonant Mode 1 (QRM1) at high load, frequency-controlled Discontinuous Conduction Mode (DCM) at medium load, and Active Burst Mode (ABM) at light load - synchronized to line frequency to suppress audible noise and flicker while maintaining dim-to-off capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| AC Input Range | 90–305 Vrms: Enables global deployment without manual voltage selection or hardware variants. |
| Power Factor (PF) | Up to 0.99 typ.: Meets IEC61000-3-2 Class C requirements for lighting equipment without external PFC stages. |
| Total Harmonic Distortion (THD) | < 10% typ.: Reduces upstream transformer heating and avoids grid compliance penalties. |

| Standby Power | 60 mW typ.: Complies with EU ErP Lot 9 and ENERGY STAR® v2.1 requirements for LED drivers. |
| Dimming Range | 1–100%: Achieved via PWM input (500 Hz–2 kHz) with configurable linear/quadratic curve and dim-to-off option. |
| Output Protection | Adaptive OVP per UL1310 Class 2: Dynamically adjusts threshold based on LED string configuration to ensure 54 Vmax compliance. |
Pinout & Package
XDPL8210XUMA1 is housed in a PG-DSO-8 (150 mil) thermally enhanced SOIC package with exposed pad for improved thermal dissipation in enclosed LED driver housings.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ZCD | Zero-crossing & voltage sensing input | Connects to auxiliary winding to detect transformer demagnetization, estimate Vout, and synchronize switching to AC line zero-crossings. |
| PWM | Dimming control input | Accepts isolated 0–10 V or MCU-generated PWM (500 Hz–2 kHz); configures dimming curve, min current, and dim-to-off behavior. |
| CS | Current sense input | Monitors primary-side MOSFET current via external shunt resistor to regulate output current without secondary feedback. |
| GD | Gate driver output | Drives CoolMOS™ P7 gate through external series resistor; slope configurable to optimize EMI and switching losses. |
| HV | High-voltage startup & sync input | Charges VCC during startup via internal 600 V cell; provides line synchronization signal and brown-in/out detection. |
| UART | Digital configuration interface | Two-wire UART (TX/RX shared) for in-system parameter programming (e.g., Iout,min, Pout,set, dim curve) using Infineon GUI tool. |
| VCC | Supply voltage & sensing | Internal LDO input (7–28 V); monitors supply health for UVLO/OVP and powers internal digital core and analog blocks. |
| GND | Signal ground reference | Common return path for analog sensing, digital logic, and gate drive; requires low-impedance PCB layout to avoid regulation errors. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar flyback controller with PFC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UCC28056 (Texas Instruments) | Analog PFC + flyback combo; no digital configurability, no UART interface, fixed dimming architecture. | Lacks dim-to-off, ABM, and adaptive OVP; requires external optocoupler for CC regulation. | Choose for cost-sensitive, non-dimmable designs where firmware flexibility is unnecessary. |
| ICE5QSAG (Infineon) | Quasi-resonant flyback controller only; no integrated PFC, no primary-side CC regulation, no dimming interface. | Requires separate PFC stage and secondary-side feedback; unsuitable for single-stage Class 2 LED drivers. | Choose only when PFC is handled externally and system-level cost allows dual-controller architecture. |
Compared with UCC28056 and ICE5QSAG, XDPL8210XUMA1 uniquely integrates PFC, primary-side CC regulation, digital dimming, and safety-critical adaptive protections in a single IC - reducing component count by ≥40% and enabling UL1310-compliant single-stage designs unattainable with analog alternatives.

FAQ
Is XDPL8210XUMA1 pin-compatible with earlier XDPL82xx revisions?
No. XDPL8210XUMA1 uses the PG-DSO-8 package with specific pin assignments (e.g., UART on Pin 6, HV on Pin 5) confirmed in Revision 1.1 datasheet Figure 3. Earlier versions like XDPL8208 use different pinouts and firmware - direct replacement requires PCB redesign and reconfiguration.
What external components are mandatory for basic operation?
Mandatory components include: HV startup resistor network (RHV), ZCD auxiliary winding divider (RZCD,1/RZCD,2), CS shunt resistor, GD gate resistor, VCC bulk capacitor, and optional CDM10VD for 0–10 V dimming. The UART pull-up resistor is required only if configuration is performed in-system.
Does XDPL8210XUMA1 require factory programming before use?
Yes. Fresh XDPL8210XUMA1 units ship with empty configuration memory. Output current setpoints (Iout,min/Iout,full), dimming curve, LP threshold, and protection thresholds must be programmed via Infineon's GUI tool using the UART interface before functional testing or deployment.
Can XDPL8210XUMA1 drive CoolMOS™ P7 without external gate drivers?
Yes. The GD pin delivers sufficient peak current (±1 A typical) and configurable slew rate to directly drive CoolMOS™ P7 devices up to 650 V/24 A in QRM1 mode. An external series gate resistor (typically 5–22 Ω) is required for EMI tuning and shoot-through prevention.
