Product details
Overview
ICL8002GXUMA1 from Infineon Technologies is a single-stage quasi-resonant LED controller IC integrating active PFC and primary-side flyback control for dimmable LED bulbs. It delivers >98% power factor, up to 90% system efficiency, and supports both leading- and trailing-edge phase-cut dimmers. Operates with VCC supply up to 26 V and features integrated HV startup cell for fast turn-on.
For engineers reviewing the ICL8002GXUMA1 datasheet, ICL8002GXUMA1 pinout, ICL8002GXUMA1 application, or ICL8002GXUMA1 equivalent, key selection criteria include its digital zero-crossing detection, foldback-corrected current limiting, adjustable latch-off OVP, soft-start timing, and compatibility with standard PG-DSO-8 layout in compact LED bulb designs.
Technical Context
The ICL8002GXUMA1 implements quasi-resonant (QR) switching with digital zero-crossing detection to minimize switching losses and EMI. Its primary-side regulation eliminates optocoupler and secondary-side feedback components.
It combines PFC and flyback functions in one stage using voltage-mode PWM with cycle-by-cycle peak current limitation and foldback correction. The HV pin provides constant-current pre-charging of VCC, enabling rapid start-up without auxiliary winding dependency during initial power-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Topology | Single-stage PFC + QR flyback - enables high PF (>98%) and low THD without separate PFC stage |
| Dimming Support | Leading- and trailing-edge phase-cut - ensures smooth dimming curve and minimal shimmer across commercial dimmers |
| VCC Operating Range | 10.5 V to 26 V - accommodates wide input transients and simplifies bulk capacitor sizing |
| Gate Drive Output | Typ. 0.7 A sink/source - directly drives MOSFET gates without external buffer in most 10–15 W LED bulb designs |
| Zero-Crossing Detection | Digital, delay-compensated - improves switch-on timing accuracy and reduces audible noise |
| OVP Protection | Adjustable latch-off mode - prevents LED string overvoltage via external resistor divider on ZCV pin |
| Startup Method | Integrated HV current source - charges VCC capacitor at constant current from rectified mains, eliminating startup resistor loss |
Pinout & Package
ICL8002GXUMA1 is housed in a PG-DSO-8 (SOIC-8 variant with exposed thermal pad) package, optimized for thermal dissipation in enclosed LED bulb environments. Pin 6 is internally unconnected (n.c.) and must remain floating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ZCV | Zero Crossing Input | Accepts delayed auxiliary winding signal; used for QR switch-on timing and output OVP detection |
| VR | Voltage Sense Input | Connects to rectified mains; sets peak current reference for PFC and dimming angle tracking |
| CS | Current Sense Input | Monitors primary shunt voltage for PWM off-time determination and short-winding protection |
| GD | Gate Drive Output | PWM output driving external MOSFET gate; 0.7 A drive strength supports <3 nF gate capacitance |
| HV | High-Voltage Startup Input | Draws constant current from bus to pre-charge VCC capacitor; enables fast light-on time |
| VCC | Supply Voltage Input | Power rail for internal circuitry; regulated between 10.5 V (UVLO) and 26 V (OVP) |
| GND | Ground Reference | Common return for all analog and digital blocks; requires low-impedance PCB connection to thermal pad |
Key Features
| Feature | Design Value |
|---|---|
| Digital Zero-Crossing Detection | Compensates for ringing delay to enable precise QR switching at true valley, reducing EMI and MOSFET stress |
| Foldback-Corrected Current Limit | Automatically adjusts peak current threshold vs. input voltage to maintain stable output power across universal AC input (85–265 VAC) |
| Integrated HV Startup Cell | Eliminates external high-voltage startup resistor, cutting standby power and improving reliability in sealed bulb enclosures |
| Primary-Side Regulation | Removes optocoupler and TL431, reducing BOM count and enabling compact, cost-sensitive retrofit bulb designs |
| Adjustable Latch-Off OVP | Configurable via external resistor on ZCV pin - protects LEDs from open-circuit failure without requiring secondary sensing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-stage PFC + QR flyback LED controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICE3B0565J | Lacks integrated HV startup; requires external startup resistor and auxiliary winding for VCC generation | No native phase-cut dimming support; needs external dimming interface circuitry | Preferred when legacy design reuse or lower unit cost outweighs dimmer compatibility and startup speed requirements |
| BP57711 | Fixed-frequency PWM (not QR); higher switching losses and EMI; no digital zero-crossing detection | Supports only trailing-edge dimmers; exhibits visible shimmer below 20% dim level | Selected for ultra-low-cost non-dimmable bulbs where PF >0.9 and efficiency >85% are sufficient |
Compared with ICE3B0565J and BP57711, the ICL8002GXUMA1 uniquely integrates HV startup, digital zero-crossing, and foldback correction-enabling faster turn-on, broader dimmer compatibility, and tighter output regulation across universal input without secondary feedback.

FAQ
What is the purpose of the HV pin on the ICL8002GXUMA1?
The HV pin provides a constant-current path from the rectified mains bus to charge the VCC capacitor during startup. This integrated HV startup cell eliminates the need for an external high-voltage resistor, reducing standby power loss and improving reliability in thermally sealed LED bulb enclosures. It activates automatically when bus voltage exceeds ~150 V.
How does the ICL8002GXUMA1 achieve power factor correction without a separate PFC stage?
It uses primary-side quasi-resonant flyback control with voltage-mode PWM and real-time input voltage sensing at the VR pin. By modulating peak primary current in proportion to the instantaneous rectified line voltage, it shapes input current to closely follow the sinusoidal waveform-achieving >98% PF and <15% THD without auxiliary PFC circuitry or boost inductor.
Can the ICL8002GXUMA1 support both leading- and trailing-edge dimmers?
Yes-the device includes adaptive phase-cut detection logic that identifies dimmer type during the first half-cycle and configures internal timing accordingly. Its precise digital zero-crossing detection and programmable ringing suppression window ensure stable operation with both TRIAC-based (leading-edge) and electronic (trailing-edge) dimmers across full dimming range.
What protection features are built into the ICL8002GXUMA1?
It integrates VCC over/under-voltage lockout, cycle-by-cycle peak current limiting with foldback correction, auto-restart short-circuit protection, and adjustable latch-off output overvoltage protection triggered via the ZCV pin. All protections operate independently of secondary feedback, ensuring robust fault response even if LED string opens or shorts.
