Product details
Overview
ICB1FL02GXUMA2 from Infineon Technologies is a Smart Ballast Control IC for fluorescent lamp ballasts, integrating PFC preconverter (DCM), half-bridge inverter control, and HV level-shift gate drivers in a single PG-DSO-18-2 package. It delivers adjustable preheat time (0–2000 ms), run frequency (20–100 kHz), and end-of-life detection via dual ±lamp voltage thresholds. Used in T5 electronic ballasts for commercial lighting systems with multi-lamp topologies.
For engineers reviewing the ICB1FL02GXUMA2 datasheet, ICB1FL02GXUMA2 pinout, ICB1FL02GXUMA2 application, or ICB1FL02GXUMA2 equivalent, key selection criteria include its integrated PFC zero-current detection (PFCZCD), dual lamp voltage sensing (LVS1/LVS2), self-adapting ignition time (40–235 ms), resistor-programmable timing, and halogen-free RoHS-compliant PG-DSO-18-2 packaging.
Technical Context
The ICB1FL02GXUMA2 implements a digitally assisted analog control architecture with two independent functional blocks: a DCM PFC preconverter using zero-current detection (PFCZCD) and internal loop compensation, and an inverter controller supporting preheat, ignition, and run phases with adaptive frequency scaling. It uses external resistors to set preheat time (RTPH), preheat frequency (RFPH), and run frequency (RFRUN).
Protection logic includes latched shutdown on overcurrent (1.6 V at LSCS for >400 ns), EOL detection via ±lamp voltage amplitude ratio, rectifier effect identification, and capacitive-mode operation detection - all validated for multilamp configurations without additional ICs.

| Preheat Time Range | 0 ms to 2000 ms, adjusted via RTPH resistor |
| Lamp Voltage Sensing | Dual inputs LVS1/LVS2 enable EOL detection via ±amplitude ratio and rectifier effect identification |
| Overcurrent Threshold | 1.6 V at LSCS pin triggers latched shutdown if exceeded >400 ns in any mode |

| Package | PG-DSO-18-2, halogen-free, RoHS/WEEE compliant |
Pinout & Package
ICB1FL02GXUMA2 is housed in a surface-mount PG-DSO-18-2 package (300-mil width), featuring isolated high-side and low-side sections with dedicated grounds (HSGND, GND) and supply rails (HSVCC, VCC).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LSCS (Pin 1) | Inverter low-side current sense | Senses MOSFET source current; 0.8 V threshold enables ignition frequency stepping, 1.6 V triggers latched shutdown |
| LSGD (Pin 2) | Inverter low-side gate drive | Drives low-side MOSFET gate with soft turn-on (220 ns rise) and fast turn-off (<50 ns fall); 1800 ns dead time vs HSGD |
| VCC (Pin 3) | Logic & low-side supply | 14 V turn-on / 10.5 V UVLO; internal 16 V zener clamp; requires local ceramic decoupling |
| GND (Pin 4) | Controller ground reference | Common return for VCC, LSGD, PFCCS, PFCZCD, and logic circuits |
| PFCGD (Pin 5) | PFC MOSFET gate drive | Drives boost switch with soft turn-on and fast turn-off; optimized for DCM/CritCM transitions |
| PFCCS (Pin 6) | PFC current sense | 1 V threshold disables PFCGD until ZCD signal confirms inductor current zero crossing |
| PFCZCD (Pin 7) | PFC zero-current detector | Detects inductor current zero-crossing via auxiliary winding; hysteresis (0.5 V/1.5 V) prevents noise false triggers |
| PFCVS (Pin 8) | PFC bus voltage sense | Monitors intermediate DC bus; thresholds at 0.375 V (15%), 1.83 V (73%), 2.725 V (109%) of 2.5 V reference |
| RFRUN (Pin 9) | Run frequency programming | Resistor to GND sets inverter operating frequency during steady-state lamp operation |
| RFPH (Pin 10) | Preheat frequency programming | Resistor to GND (with RFRUN) sets inverter frequency during preheat phase |
| RTPH (Pin 11) | Preheat time programming | Resistor to GND sets preheat duration from 0 to 2000 ms |
| RES (Pin 12) | Lamp removal restart enable | Enables automatic restart after lamp removal; discharge resistor value determines restart delay |
| LVS1/LVS2 (Pins 13–14) | Lamp voltage sensing | Dual inputs detect lamp voltage polarity and amplitude for EOL, rectifier effect, and capacitive-mode diagnostics |
| HSGND (Pin 17) | High-side floating ground | Reference for HSVCC and HSGD; electrically isolated from GND to support level-shifted high-side drive |
| HSGD (Pin 19) | Inverter high-side gate drive | Level-shifted drive for high-side MOSFET; synchronized with LSGD via 1800 ns dead time |
| HSVCC (Pin 18) | High-side supply | Provides power to high-side driver section; referenced to HSGND, not GND |
Key Features
| Feature | Design Value |
|---|---|
| Integrated PFC loop compensation | Eliminates external compensation network; reduces BOM count and layout sensitivity in DCM boost designs |
| Resistor-programmable timing | Preheat time, preheat frequency, and run frequency set by three external resistors - no EEPROM or digital interface required |
| End-of-life detection | Adjustable ±voltage thresholds on LVS1/LVS2 enable reliable lamp EOL identification in multi-lamp systems without added comparators |
| Capacitive-mode operation detection | Identifies unsafe capacitive resonance conditions during ignition or fault states, preventing MOSFET overstress |
| HV level-shift half-bridge driver | Integrated high-side driver with HSGND/HSVCC references eliminates need for external bootstrap or isolated supplies |
Applications
| Commercial T5 Fluorescent Lighting | Industrial Multi-Lamp Ballasts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fluorescent lamp ballast control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRS2166DSPBF | Integrated 600 V half-bridge driver + PFC controller; no dedicated LVS1/LVS2 pins; EOL detection requires external circuitry | Lacks native dual-lamp voltage sensing and rectifier effect detection; suited for single-lamp or non-EOL-critical designs | Select when cost-sensitive single-lamp ballasts prioritize integration over diagnostic depth |
| UCC3305D | Analog-only ballast controller; no PFC section; requires external PFC IC or discrete PFC stage | Designed for simpler, lower-cost inverters where PFC is handled upstream or omitted | Select when PFC is implemented separately and lamp diagnostics are minimal |
Compared with IRS2166DSPBF and UCC3305D, ICB1FL02GXUMA2 uniquely integrates DCM PFC, dual-lamp voltage sensing, and multilamp-capable EOL/rectifier diagnostics in one PG-DSO-18-2 device - reducing total component count by ≥40% in T5 ballast designs requiring regulatory compliance and field reliability.

FAQ
What is the minimum preheat time achievable with ICB1FL02GXUMA2?
The minimum preheat time is 0 ms, achieved by connecting RTPH (Pin 11) directly to GND. This bypasses preheating entirely, enabling direct ignition - suitable only for lamps rated for instant-start operation and verified in system-level thermal testing.
Does ICB1FL02GXUMA2 support 120 V AC input operation?
Yes - the IC operates with 90–270 V AC input range. Its PFC section regulates the DC bus to ~380–400 V regardless of line voltage, and internal UVLO (10.5 V) and overvoltage (2.725 V at PFCVS) thresholds ensure robust startup and protection across global mains voltages.
How is the dead time between HSGD and LSGD enforced?
Dead time is fixed at 1800 ns internally and cannot be adjusted. It is generated by dedicated logic between the high-side and low-side gate drive paths to prevent shoot-through, independent of external resistor values or operating frequency.
Can LVS1 and LVS2 be used for dimming feedback?
No - LVS1 and LVS2 are dedicated to lamp health diagnostics (EOL, rectifier effect, capacitive mode). They lack ADC conversion, programmable gain, or feedback loop integration; dimming must be implemented externally via RFRUN/RFPH resistor modulation or PWM injection at RES.
