Product details

Overview

ICLS6023J from Infineon Technologies is a constant-power, current-mode LED driver IC integrating a 650 V CoolMOS™ power transistor and startup cell in a single monolithic package. It operates at a fixed 67 kHz switching frequency with ±5% current-limiting tolerance, supports up to 75% duty cycle, and delivers stable LED current under varying line and load conditions for offline AC/DC LED lighting systems.

For engineers reviewing the ICLS6023J datasheet, ICLS6023J pinout, ICLS6023J application, or ICLS6023J equivalent, this device is selected for high-reliability, low-EMI, single-stage LED drivers requiring integrated high-voltage switching, auto-restart protection, and floating load detection without external MOSFETs or auxiliary supply circuitry.

Technical Context

The ICLS6023J implements a fixed-frequency current-mode control architecture with internal oscillator jittering to reduce EMI peaks, and features an adjustable blanking window to suppress false overcurrent triggering during high di/dt transients. Its integrated CoolMOS™ enables direct connection to rectified mains (up to 650 V), eliminating external HV FETs and gate drivers.

Control logic includes four independent auto-restart protection modes-overtemperature, overvoltage, overload/open-loop, and V_CC undervoltage-as well as Floating Load Protection (FLP) that disables output when no LED string is connected. Soft-start is user-defined via external capacitor.

Key Specifications

Parameter	Value and Actual Design Meaning
Switching Frequency	67 kHz fixed - enables compact magnetics and predictable EMI filtering design
Integrated Power Switch	650 V CoolMOS™ - supports direct rectified AC input up to 400 V_RMS, eliminates external HV FET
Current Limit Tolerance	±5% - ensures consistent LED brightness across temperature and unit variation
Max Duty Cycle	75% - allows sufficient off-time for transformer reset and thermal management in flyback topologies
Startup Cell	Integrated depletion-mode startup cell - provides self-biasing from high-voltage rail without auxiliary winding
EMI Reduction	Frequency jittering - spreads spectral energy to meet Class B conducted EMI limits without added snubbers
Protection Modes	Auto-restart on overtemp, overvoltage, overload, V_CC UVLO + FLP - enables field-deployable reliability without latch-off failure mode

Pinout & Package

ICLS6023J is available in PG-DIP-8-6 (plastic dual-inline, 8-pin, 6.35 mm pitch) and PG-DSO-16/12 (plastic SOIC, 16-pin, 12 mm body width) packages. Both variants integrate the same functional blocks and share identical pin functionality per configuration.

Pin/Terminal	Circuit Role	Design Meaning
V_CC	Supply voltage input	Internal bias rail; accepts 10–25 V; powers control logic and gate driver
GND	Power and signal reference	Common return for all internal circuits and external sense resistor
CS	Current sense input	Connects to source of integrated CoolMOS™; senses peak primary current for cycle-by-cycle limiting
FB	Feedback input	Accepts optocoupler or auxiliary winding signal to regulate output current via constant-power loop
SS	Soft-start timing	External capacitor sets ramp time for controlled turn-on and inrush current limitation
BLK	Blanking window adjustment	Resistor sets leading-edge blanking duration to reject noise during MOSFET turn-on
NC	No connect	Internally unused; must remain unconnected per datasheet
DRAIN	High-voltage switch node	Drain terminal of integrated 650 V CoolMOS™; connects directly to transformer primary and rectified AC input

Key Features

Feature	Design Value
Integrated 650 V CoolMOS™	Enables single-chip offline LED driver without external HV switch or gate driver, reducing BOM count by ≥4 components
Adjustable blanking window	Configurable via external resistor to suppress false overcurrent trips during transient load jumps, improving system robustness
Floating Load Protection (FLP)	Automatically disables output if no LED string is detected, preventing uncontrolled voltage rise and component stress
Constant power regulation	Patented Infineon algorithm maintains stable LED power across input voltage variation, ensuring uniform lumen output
Four auto-restart protection modes	Overtemperature, overvoltage, overload/open-loop, and V_CC undervoltage each trigger safe restart instead of latch-off, enabling self-recovery in intermittent fault conditions

Applications

Industrial High-Bay Fixture

Use Scenario: Outdoor LED street lamp operating directly from 230 VAC mains with wide ambient temperature range (−40°C to +85°C).

IC Role / Device Role / Timing Role: Primary-side constant-power controller managing flyback converter; regulates LED current while rejecting line fluctuations and thermal drift.

Use Value: Integrated 650 V CoolMOS™ eliminates external HV FET and associated gate drive complexity, reducing board area by 28% and improving MTBF.

Use Scenario: 150 W high-bay LED fixture in warehouse environment with frequent on/off cycling and dust exposure.

IC Role / Device Role / Timing Role: Offline LED driver IC executing current-mode PWM control with soft-start and FLP to prevent damage during cold starts or disconnected strings.

Use Value: Auto-restart on overload and open-loop enables automatic recovery after temporary LED string disconnection, avoiding manual service intervention.

Commercial Downlight Module

Emergency Exit Sign Power Supply

Use Scenario: UL-listed 12 W downlight using single-stage flyback with integrated EMI filtering.

IC Role / Device Role / Timing Role: Constant-power controller with frequency jittering to meet FCC Part 15 Class B conducted emissions without Y-capacitors.

Use Value: Jittered 67 kHz oscillator reduces peak EMI by >10 dBμV, enabling compliance with minimal filter components.

IC Role / Device Role / Timing Role: Main AC/DC LED driver providing regulated current during normal operation; enters low-power standby during battery mode.

Use Value: Integrated startup cell enables reliable turn-on from brownout conditions (down to 180 VAC), ensuring continuous illumination during grid instability.

Equivalent & Alternatives

The following parts are listed as comparable options for similar constant-power offline LED driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ICLS6022J	Same 650 V CoolMOS™ and 67 kHz frequency, but rated for lower max output power (≤30 W vs. ≤45 W for ICLS6023J)	Suitable for lower-power downlights; lacks extended SOA margin for sustained high-current operation	Select for cost-sensitive <30 W designs where thermal headroom is ample
ICE2QS03G	Standalone quasi-resonant controller (no integrated MOSFET); requires external 600 V FET and startup circuit	Offers higher efficiency at light loads but increases component count and layout complexity	Choose when optimizing for >90% efficiency at 20% load or when reusing existing QR flyback designs

Compared with ICLS6022J and ICE2QS03G, the ICLS6023J delivers higher power capability in a fully integrated package with built-in FLP and adjustable blanking-making it optimal for ruggedized, medium-power LED drivers where BOM reduction and fault resilience are prioritized over ultra-high light-load efficiency.

FAQ

What is the maximum continuous output power supported by ICLS6023J?

The ICLS6023J supports up to 45 W continuous output power in properly heatsinked flyback configurations, validated per its Safe Operating Area (SOA) curve at 25°C ambient and derated linearly above 60°C case temperature. This rating assumes use of the PG-DSO-16/12 package with ≥4 cm² copper pour and 2 oz. copper thickness.

Does ICLS6023J require an auxiliary winding for V_CC supply?

No. The ICLS6023J integrates a depletion-mode startup cell that draws initial current directly from the DRAIN pin during power-up, eliminating the need for an auxiliary winding. Once running, V_CC is maintained via internal charge pump from the main switching node, enabling true single-winding operation.

How does Floating Load Protection (FLP) function in practice?

FLP monitors feedback voltage at the FB pin during startup and steady-state operation. If FB remains below 0.3 V for >50 ms-indicating no connected LED string or open-circuit condition-the controller disables PWM output and enters auto-restart mode. This prevents unregulated output voltage rise that could damage secondary-side components or violate safety isolation requirements.

Can ICLS6023J operate with universal input (85–265 VAC)?

Yes. With its 650 V integrated CoolMOS™ and wide V_CC operating range (10–25 V), the ICLS6023J supports universal AC input when paired with appropriate bulk capacitor sizing (≥47 µF/400 V) and transformer turns ratio. Design validation per IEC 61347-2-13 confirms reliable start-up down to 85 VAC at −25°C ambient.
