Product details

Overview

ICL5102XUMA2 from Infineon Technologies is a dual-stage PFC + resonant half-bridge controller for LED drivers, integrating CrCM/DCM PFC and LLC/LCC HB control in one DSO-16 package. It delivers up to 94% system efficiency, <5% THD at 30% load, universal AC input (90–305 V_rms), and supports active burst mode for <300 mW standby power in commercial lighting up to 350 W.

For engineers reviewing the ICL5102XUMA2 datasheet, ICL5102XUMA2 pinout, ICL5102XUMA2 application, or ICL5102XUMA2 equivalent, key selection criteria include CrCM+DCM PFC operation, resonant HB frequency range (up to 500 kHz with 1.3 MHz soft-start), integrated high-side gate driver, capacitive mode protection, and comprehensive auto-restart protections including OVP, OCP, OPP, OTP, and brown-out detection.

Technical Context

The ICL5102XUMA2 implements a harmonized two-stage architecture: its multi-mode PFC stage uses constant-on-time CrCM at medium-to-heavy loads and transitions to DCM at light loads to maintain high PF and low THD (<5% down to 30% load). The resonant HB stage supports both LLC and LCC topologies with fixed or variable-frequency control via external R_F, enabling optimal ZVS across wide load ranges.

It integrates independent gate drivers-PFCGD (low-side PFC MOSFET), LSGD/LSGS (HB low-side), and HSGD (floating high-side HB MOSFET)-with dedicated sensing inputs (PFCCS, LSCS, PFCZCD, PFCVS, OVP, BO, OTP) and protection logic that triggers auto-restart on fault conditions including capacitive mode, bus over-voltage (dual-level), and output over-power.

Pinout & Package

ICL5102XUMA2 is housed in a PG-DSO-16 (150-mil) thermally enhanced SOIC package with exposed pad for improved heat dissipation in high-power LED driver applications.

Pin/Terminal	Circuit Role	Design Meaning
LSGD (Pin 1)	HB Low-Side Gate Driver Output	Directly drives HB low-side MOSFET gate through external resistor; enables precise timing control of half-bridge switching node
LSCS (Pin 2)	HB Current Sense Input	Connects to shunt resistor at low-side MOSFET source; provides cycle-by-cycle current limiting and OCP1/OCP2 detection
VCC (Pin 3)	Main IC Supply Input	Primary bias supply (7–20 V); UVLO threshold at 12.5 V turn-on / 9.5 V turn-off ensures stable startup under varying line conditions
GND (Pin 4)	Signal Ground Reference	Common return path for PFC and HB control circuitry; separate from HSGND to isolate floating driver domain
PFCGD (Pin 5)	PFC Gate Driver Output	Drives boost PFC MOSFET gate; optimized for fast rise/fall times to minimize switching losses in CrCM operation
PFCCS (Pin 6)	PFC Current Sense Input	Monitors PFC inductor peak current via shunt; enables accurate on-time calculation and over-current shutdown
PFCZCD (Pin 7)	PFC Zero-Cross Detection	Interfaces with PFC auxiliary winding to detect inductor current zero-crossing - critical for CrCM boundary detection
PFCVS (Pin 8)	PFC Bus Voltage Sense	High-impedance input for resistive divider from PFC output; regulates 385–400 V DC bus with ±1% accuracy
RF (Pin 9)	HB Min. Frequency Set	External resistor to GND sets minimum HB operating frequency - defines lower bound for variable-frequency control
BM (Pin 10)	Active Burst Mode Control	Configures ABM entry/exit thresholds via opto-coupler feedback; enables ultra-low standby power without audible noise
OTP (Pin 11)	External Over-Temperature Input	Accepts NTC thermistor voltage divider; triggers auto-restart OTP shutdown at user-defined temperature threshold
BO (Pin 12)	Brown-In/Out Detection	Monitors rectified AC line via resistor divider; initiates controlled shutdown during brown-out and restarts after recovery
OVP (Pin 13)	Output Over-Voltage Protection	Senses secondary-side voltage via auxiliary winding; provides fast OVP response (<1 µs) to protect LEDs and downstream circuitry
HSGND (Pin 14)	High-Side Floating Ground	Reference for HSVCC/HSGD; electrically isolated from main GND to support bootstrap high-side drive
HSVCC (Pin 15)	High-Side Bootstrap Supply	Charged via external diode/capacitor; supplies floating driver stage (V_HSGD = HSVCC − HSGND)
HSGD (Pin 16)	HB High-Side Gate Driver Output	Drives floating high-side MOSFET; integrated level shifter and dead-time control prevent shoot-through

Key Features

Feature	Design Value
Integrated PFC + Resonant HB Controller	Reduces BOM count by >30% vs. discrete controllers; eliminates inter-stage timing mismatch and simplifies PCB layout
Multi-Mode PFC with THD Optimization	Dynamic CrCM-to-DCM transition and adaptive zero-cross correction achieve <5% THD even at 30% load
Resonant HB with Self-Adaptive Dead Time	Adjusts dead time in real time based on switching node dv/dt - ensures robust ZVS across line/load/temperature variations
Capacitive Mode Protection	Detects unsafe capacitive resonance region in LLC/LCC and forces frequency shift or shutdown - prevents MOSFET failure
Dual-Level PFC Bus OVP	Level 1 (fast, latch-off) and Level 2 (slower, auto-restart) OVP provide graded response to transient overvoltage events

Equivalent & Alternatives

The following parts are listed as comparable options for similar PFC + resonant half-bridge controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
UCC28070DWR	Two-phase interleaved CrCM PFC only; requires external HB controller (e.g., UCC25630x) - no integrated resonant HB stage	Used in higher-power (>500 W), multi-kW systems where interleaving reduces input ripple; not suitable for compact single-chip LED drivers	Select when PFC performance at >400 W and thermal distribution across two controllers outweighs BOM simplicity
ICE2PCS01G	Single-stage quasi-resonant flyback + PFC combo; no resonant half-bridge support - limited to <100 W output	Targeted at low-cost, low-power LED bulbs and drivers; lacks ABM, capacitive mode protection, and universal HV input capability	Choose only for cost-sensitive sub-100 W applications where 94% efficiency and <5% THD are not required

Compared with UCC28070DWR and ICE2PCS01G, the ICL5102XUMA2 uniquely integrates full PFC + resonant HB control in one DSO-16 package, delivering superior THD optimization, ABM-enabled standby, and industrial-grade protection - making it the only viable option for 150–350 W high-efficiency LED drivers requiring compactness and certification readiness.

FAQ

What is the recommended external bootstrap capacitor value for HSVCC in ICL5102XUMA2?

The recommended bootstrap capacitor between HSVCC and HSGND is 100 nF ceramic with X7R dielectric and ≥25 V rating. This value ensures stable high-side driver operation across 50–500 kHz switching frequencies and maintains sufficient charge during maximum duty cycle at 305 V_rms input. Layout must minimize loop inductance using short, wide traces adjacent to the IC.

Does ICL5102XUMA2 support LLC and LCC topologies interchangeably?

Yes - the resonant HB controller supports both LLC and LCC topologies via the same pin configuration and control algorithm. Frequency sweep behavior, dead-time adaptation, and capacitive mode detection are topology-agnostic. Selection depends solely on transformer design: LLC for tighter regulation and LCC for higher efficiency at light loads, both validated per Infineon's AN2019-05 application note.

How does the dual-level PFC bus OVP function differ from standard OVP?

ICL5102XUMA2 implements two independent OVP thresholds on PFCVS: Level 1 (420 V) triggers immediate latch-off shutdown for catastrophic overvoltage; Level 2 (405 V) initiates auto-restart mode with reduced frequency and soft-start reset. This staged response protects bulk capacitors during transient surges while maintaining system availability during recoverable overvoltage events.

Can the ABM (Active Burst Mode) be disabled for continuous operation?

Yes - ABM is disabled by leaving BM pin open or connecting it directly to GND. In this state, the HB stage operates in continuous variable-frequency mode down to ~20 kHz at no-load, eliminating burst-related acoustic noise but increasing standby power to ~450 mW. For <300 mW standby, BM must be connected to an opto-coupler feedback network as shown in Figure 3 of the datasheet.
