Product details
Overview
ICL5101XUMA1 from Infineon Technologies is a resonant controller IC with integrated PFC for LED drivers, combining CrCM/DCM PFC and self-adaptive half-bridge LLC control in one PG-DSO-16-23 package. It delivers >99% power factor, <5% THD, 94% peak efficiency, ultra-fast start-up (<200 ms), and operates from -40 °C to +125 °C for outdoor-rated luminaires above 50 W.
For engineers reviewing the ICL5101XUMA1 datasheet, ICL5101XUMA1 pinout, ICL5101XUMA1 application, or ICL5101XUMA1 equivalent, key selection criteria include its dual-mode PFC (CrCM/DCM), integrated 650 V high-side driver, self-adaptive dead time (500 ns–1.0 µs), capacitive-mode detection, and resistor-based parameter tuning for rapid design-in.
Technical Context
The ICL5101XUMA1 implements a two-stage architecture: a PFC preconverter operating in critical conduction mode (CrCM) at nominal load and discontinuous conduction mode (DCM) down to 0.1% load to eliminate audible noise, with adjustable THD compensation via zero-crossing detection. Its resonant half-bridge stage features fully integrated 650 V high-side and low-side gate drivers, self-adaptive dead-time control, and real-time capacitive-mode detection using LSCS pin thresholds (-50 mV, 2.0 V).
Protection logic includes latched shutdown on overcurrent (>0.8 V for >500 ns at LSCS), overtemperature (OTP pin), secondary-side overvoltage (OVP pin), and magnetic saturation handling during startup. All operating parameters-including RUN frequency (RFM pin), PFC current limit, and bus voltage thresholds-are set by external resistors without programming interfaces.
Key Specifications

Pinout & Package
ICL5101XUMA1 is housed in a PG-DSO-16-23 thermally enhanced SOIC-16 package with exposed pad, optimized for high-power LED driver PCB layouts requiring efficient heat dissipation and creepage/clearance compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LSGD (Pin 1) | Low-side gate drive output | Drives low-side MOSFET with soft turn-on (245 ns rise) and fast turn-off (<50 ns fall); enables controlled di/dt and reduced EMI |
| LSCS (Pin 2) | Low-side current sense input | Detects inverter overcurrent (0.8 V threshold), capacitive operation (-50 mV), and reverse-recovery spikes (2.0 V), eliminating need for external filters |
| VCC (Pin 3) | IC supply voltage input | 14.0 V turn-on / 10.6 V UVLO; internal 16.3 V Zener clamp supports stable bias under transient bus conditions |
| GND (Pin 4) | Ground reference | Common return for VCC, gate drives, and sense signals-must be low-inductance connection to minimize noise coupling |
| PFCGD (Pin 5) | PFC gate drive output | Drives boost MOSFET with same soft-switching profile as LSGD; supports fixed-on-time startup before ZCD lock |
| PFCCS (Pin 6) | PFC current sense input | Monitors boost inductor current for CrCM/DCM transition and cycle-by-cycle current limiting |
| PFCZCD (Pin 7) | PFC zero-current detection | Enables CrCM operation by detecting inductor demagnetization; initiates next switching cycle at valley |
| PFCVS (Pin 8) | PFC bus voltage sense | Provides feedback for PFC output regulation, OVP, and bus undervoltage protection |
| RFM (Pin 9) | Resonant frequency setting | Resistor-connected pin sets minimum LLC run frequency; defines lower boundary of variable-frequency operation |
| n.a. (Pin 10) | Not applicable | Must remain unconnected per datasheet; no internal function or pull-up/down |
| n.a. (Pin 11) | Not applicable | Must be tied to GND; unused pin with mandatory grounding for EMC stability |
| OVP (Pin 12) | Secondary overvoltage protection | External resistor divider triggers latch-off if isolated output exceeds safe LED string voltage |
| OTP (Pin 13) | Overtemperature protection input | NTC-based thermal monitoring; latches off IC if system hot spot exceeds threshold |
| HSGND (Pin 14) | High-side driver ground | Floating ground reference for 650 V high-side driver; requires careful layout to minimize dv/dt coupling |
| HSVCC (Pin 15) | High-side supply voltage | Charged via bootstrap diode/capacitor; powers high-side driver stage independently of VCC |
| HSGD (Pin 16) | High-side gate drive output | Integrated 650 V driver eliminates external level shifter; enables compact half-bridge implementation |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar resonant LED driver controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UCC28064ADRMT | Dual-phase CrCM PFC + LLC controller; no integrated high-side driver-requires external 600 V level shifter and gate driver | Better suited for multi-kW industrial LED systems where layout flexibility and thermal separation outweigh integration benefits | Select when designing >300 W systems needing independent PFC/LLC optimization or higher voltage tolerance than 650 V |
| IRS2505LTRPBF | Standalone LLC resonant controller only; no PFC functionality-requires external PFC IC or passive solution | Used in cost-sensitive, medium-power LED drivers where PFC is handled separately or omitted per local regulations | Select only when PFC is implemented externally or not required; adds ≥4 components and increases board area vs. ICL5101XUMA1 |
Compared with UCC28064ADRMT and IRS2505LTRPBF, ICL5101XUMA1 provides full PFC+LLC integration with on-die 650 V high-side driver, enabling smallest footprint and lowest component count for 50–200 W outdoor LED drivers-while maintaining superior low-load THD performance and thermal robustness.

FAQ
What is the maximum output power supported by ICL5101XUMA1?
The ICL5101XUMA1 is validated for LED drivers up to 200 W in typical reference designs, with thermal and electrical margins allowing robust operation at 110–150 W continuous output. Its 650 V high-side driver and -40 °C to +125 °C rating enable reliable use in 100–200 W outdoor luminaires, though system-level validation is required for >150 W due to PCB layout and heatsinking dependencies.
Does ICL5101XUMA1 support analog or PWM dimming?
ICL5101XUMA1 does not include native dimming interface circuitry; dimming is implemented externally via the feedback loop-typically by injecting current into the VREF node or modulating the PFC bus voltage. Reference designs confirm compatibility with 0–10 V, DALI, and PWM dimming schemes when paired with appropriate optocoupler or error amplifier configurations.
How is overtemperature protection implemented?
Overtemperature protection uses Pin 13 (OTP) as an NTC thermistor input: a voltage divider formed by the NTC and a pull-up resistor feeds a comparator inside the IC. When the sensed voltage crosses the threshold (corresponding to ~125 °C at the NTC location), the IC enters latched shutdown. The NTC must be placed near critical hot spots-such as the main transformer or output rectifier-to provide accurate system-level thermal monitoring.
Can ICL5101XUMA1 operate with non-universal AC inputs?
Yes-ICL5101XUMA1 supports universal input (90–305 VAC) by default, but its PFC section can be configured for fixed-input ranges (e.g., 230 VAC-only) by adjusting the PFCVS resistor divider and RFM timing resistor. This maintains >99% PF and <5% THD within the selected range while simplifying EMI filter design for region-specific deployments.
