Product details

Overview

ICL5102HVXUMA1 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 IC. It supports universal AC input (90–480 V_rms), achieves ≤5% THD at 30% load, delivers up to 94% system efficiency, and enables <300 mW standby power via burst mode. Used in commercial/industrial offline LED drivers up to 350 W.

For engineers reviewing the ICL5102HVXUMA1 datasheet, ICL5102HVXUMA1 pinout, ICL5102HVXUMA1 application, or ICL5102HVXUMA1 equivalent, key selection criteria include multi-mode 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 ICL5102HVXUMA1 implements a synchronized two-stage architecture: the PFC stage operates in Critical Conduction Mode (CrCM) for full-load efficiency and Discontinuous Conduction Mode (DCM) for light-load optimization, both regulated via internal PI compensator with 2.5 V reference at PFCVS. The resonant HB stage supports fixed or variable-frequency control (via RF and BM pins), includes self-adaptive dead-time adjustment, and enables burst mode for sub-300 mW standby.

It integrates dedicated high-side (HSGD/HSVCC/HSGND) and low-side (LSGD/LSCS) gate drivers, separate current-sense inputs for PFC (PFCCS) and HB (LSCS), and independent voltage sensing paths for PFC bus (PFCVS), output OVP (OVP), and input brown-in/out (BO), enabling robust line regulation and fault response across wide AC input ranges.

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
UCC28070DR	Standalone CrCM PFC controller only; requires external HB controller (e.g., UCC25630x) and discrete gate drivers	Higher BOM count and board area; less integrated protection coordination between stages	Preferred when design requires independent optimization of PFC and HB stages or legacy topology reuse
ICE3PCS01G	Single-stage quasi-resonant flyback + PFC combo; no resonant half-bridge support; max output ~150 W	Limited to lower-power applications; lacks burst mode, capacitive mode protection, and HB high-side driver	Suitable for cost-sensitive <150 W LED drivers where LLC/LCC topology and high-density integration are not required

Compared with UCC28070DR and ICE3PCS01G, ICL5102HVXUMA1 uniquely integrates CrCM/DCM PFC and resonant HB control-including high-side gate driver, capacitive mode protection, and burst mode-enabling higher power density, lower THD, and simplified safety certification for 250–350 W LED drivers.

FAQ

What is the purpose of the RF pin on ICL5102HVXUMA1?

The RF pin sets the minimum resonant half-bridge switching frequency via an external resistor to GND. Its value directly determines the lowest operating frequency in variable-frequency mode and influences burst mode behavior. Typical values range from 100 kΩ (≈250 kHz) to 470 kΩ (≈120 kHz), and it must be used with proper decoupling to avoid frequency jitter.

How does the ICL5102HVXUMA1 implement capacitive mode protection?

Capacitive mode protection monitors phase relationship between HB resonant tank voltage and current using internal timing logic. When the phase shift crosses a predefined threshold indicating operation beyond series resonance into capacitive region, the IC disables HB switching and enters fault recovery with auto-restart after a timeout-preventing MOSFET shoot-through and thermal runaway.

Can the ICL5102HVXUMA1 support both LLC and LCC resonant topologies?

Yes-the ICL5102HVXUMA1 supports both LLC and LCC topologies via its resonant HB controller. Its variable-frequency control, self-adaptive dead time, and burst mode operate identically across both configurations. External tank component selection (e.g., resonant capacitor ratio, magnetizing inductance) determines topology choice; no internal configuration is required.

What is the function of the PFCZCD pin and how is it connected?

The PFCZCD pin detects zero-crossing of the PFC inductor current using a resistor-connected auxiliary winding on the PFC boost choke. It provides timing reference for CrCM operation. Connection requires a voltage divider (typically 100 kΩ + 10 kΩ) to limit input voltage to <5.5 V, with internal hysteresis ensuring noise immunity during transition detection.
