Product details
Overview
XDPL8105XUMA1 from Infineon is a digital flyback controller IC with integrated PFC for single-stage AC-DC LED drivers, delivering ±3% output current regulation, 0.99 typical power factor, and up to 91% efficiency across 85–305 VAC input. It implements primary-side constant-current control, eliminating secondary-side feedback, and supports both microcontroller-based PWM dimming and isolated 0–10 V dimming via CDM10V.
For engineers reviewing the XDPL8105XUMA1 datasheet, XDPL8105XUMA1 pinout, XDPL8105XUMA1 application, or XDPL8105XUMA1 equivalent, key selection considerations include primary-side current sensing accuracy, QR/DCM/ABM multi-mode operation, configurable gate drive slew rate for EMI reduction, and UART-based parameter tuning via DIM/UART pin.
Technical Context
The XDPL8105XUMA1 executes real-time digital control of quasi-resonant (QR), discontinuous conduction mode (DCM), and active burst mode (ABM) flyback topologies. Its embedded microcontroller samples ZCD (auxiliary winding voltage) for zero-crossing detection, input/output voltage monitoring, and demagnetization timing - enabling precise primary-side output current calculation without optocouplers.
It integrates a 600 V high-voltage startup cell on HV pin, supports dual-function DIM/UART pin for configuration or analog dimming input (0.1–2.0 V), and provides programmable protection thresholds including OCP1/OCP2, over/undervoltage lockouts, and adaptive thermal shutdown based on internal temperature sensor readings.

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 + QR flyback combo; no digital configurability, fixed protection thresholds, no UART interface. | Lacks primary-side current regulation accuracy (±5% vs ±3%) and dimming flexibility (no 0–10 V isolation support). | Preferred for cost-sensitive, fixed-specification LED drivers where field tuning is unnecessary. |
| ICE5QSAG | Quasi-resonant flyback controller with analog PFC; no integrated HV startup, requires external bias winding. | No built-in UART configuration or isolated dimming support; relies on optocoupler for current feedback. | Suitable when legacy analog design flow and minimal firmware dependency are prioritized. |
Compared with UCC28056DR and ICE5QSAG, XDPL8105XUMA1 delivers tighter current regulation, eliminates secondary feedback, and enables post-production parameter optimization - critical for scalable LED driver platforms requiring variant management and global compliance.

FAQ
What is the function of the DIM/UART pin?
The DIM/UART pin serves dual roles: as an analog dimming input accepting 0.1–2.0 V signals for brightness control, or as a UART interface for configuring parameters like current setpoint and protection thresholds. Voltage above 2.2 V triggers UART mode; a reset restores dimming functionality.
Does XDPL8105XUMA1 require an external optocoupler for feedback?
No. XDPL8105XUMA1 uses primary-side sensing via ZCD and CS pins to calculate output current and voltage, achieving ±3% regulation without optocouplers or secondary-side feedback components - reducing BOM cost and improving reliability.
How does the HV pin enable startup without auxiliary winding?
The HV pin connects directly to the rectified input and powers an integrated 600 V startup cell that pre-charges the VCC capacitor. Once VCC reaches operating voltage, the controller activates and transitions to normal operation - eliminating need for bias winding or startup resistors.
Can XDPL8105XUMA1 support both leading-edge and trailing-edge dimmers?
XDPL8105XUMA1 does not directly interface with phase-cut dimmers. It supports 0–10 V analog dimming (via CDM10V) or PWM dimming from a microcontroller. External dimmer interface circuits must convert phase-cut signals to compatible 0–10 V or PWM inputs.
