Product details

Overview

ICLS8023Z from Infineon Technologies is an off-line LED current mode controller IC integrating an 800 V CoolMOS™ power transistor and startup cell in a single PG-DIP-7 package. It delivers primary-side constant-current regulation for AC/DC LED drivers, supports universal input (85–265 V_AC), features patented propagation delay compensation, and enables high-efficiency flyback topology operation up to 100 kHz switching frequency.

For engineers reviewing the ICLS8023Z datasheet, ICLS8023Z pinout, ICLS8023Z application, or ICLS8023Z equivalent, key selection considerations include integrated 800 V high-voltage switch capability, leading-edge blanking with dynamic threshold, floating load protection (FLP), soft-start timing, and compliance with IEC 61000-3-2 Class C harmonic limits for LED lighting systems.

Technical Context

The ICLS8023Z implements a current-mode PWM control architecture with internal oscillator, gate driver, and analog control unit optimized for primary-side regulated LED drivers. Its integrated CoolMOS™ enables direct connection to rectified mains without external HV startup resistors, while the patented propagation delay compensation ensures accurate current sensing across temperature and line variations.

Control logic includes extendable blanking mode, odd-skip auto-restart on overcurrent, and dual-stage protection: V_CC overvoltage/undervoltage, OTP, overload, open-loop, and floating load detection. The device operates in discontinuous conduction mode (DCM) and supports light-load burst-mode operation to maintain efficiency at low output power.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	85–265 V_AC universal mains input; enables single-BOM global deployment without hardware reconfiguration.
Integrated Switch Rating	800 V drain-source breakdown voltage; eliminates need for external HV MOSFET and startup network in offline LED drivers.
Switching Frequency	Up to 100 kHz; balances EMI performance and transformer size for compact LED driver designs.
Current Sense Accuracy	±5% over temperature and line; achieved via propagation delay compensation and dynamic V_CSTH threshold.
Soft-Start Time	Typ. 12 ms; prevents inrush current and stabilizes output during power-up without external components.
Protection Features	V_CC OVP/UVLO, OTP, FLP, overload, open-loop, and overcurrent shutdown with auto-restart; reduces system-level BOM count.
Package	PG-DIP-7 (7-pin plastic dual-in-line package); provides creepage/clearance compliant with EN61347-1 for Class II LED drivers.

Pinout & Package

ICLS8023Z is housed in a PG-DIP-7 package with 7.62 mm lead pitch, creepage ≥ 8 mm, and isolation rated for 4 kV_RMS. The package supports through-hole mounting and meets RoHS-compliant Pb-free lead finish requirements.

Pin/Terminal	Circuit Role	Design Meaning
V_CC	Supply voltage input	Internal LDO input; powers control circuitry after startup; UVLO threshold = 12.5 V, OVP = 28 V.
GND	Power ground reference	Common return for control logic and current sense amplifier; isolated from power ground in layout.
FB	Feedback input	Primary-side current sense node; connects to auxiliary winding for constant-current regulation without optocoupler.
CS	Current sense input	Direct connection to source of integrated CoolMOS™; senses peak primary current for cycle-by-cycle limiting.
NC	No connect	Internally unused pin; must remain unconnected per datasheet to avoid malfunction.
DRAIN	High-voltage switch drain	Connects to rectified mains input; integrates 800 V CoolMOS™; handles full primary-side switching stress.
NC	No connect	Second internally unused pin; electrically isolated; no external connection permitted.

Key Features

Feature	Design Value
Integrated 800 V CoolMOS™	Eliminates external HV MOSFET and startup resistor network, reducing component count by ≥4 and PCB area by ~15%.
Patented Propagation Delay Compensation	Corrects timing skew between CS signal and PWM latch, enabling ±5% current regulation accuracy across –40°C to +125°C.
Floating Load Protection (FLP)	Detects open-circuit or short-circuit conditions at LED string via FB pin monitoring; triggers safe shutdown without secondary feedback.
Extendable Blanking Mode	Adjusts leading-edge blanking window dynamically based on line voltage, preventing false overcurrent trips during high-V_IN startup.
Burst-Mode Light-Load Operation	Reduces standby power to <300 mW at 230 V_AC, meeting Energy Star v2.0 and ERP Tier 2 requirements for LED lamps.

Equivalent & Alternatives

The following parts are listed as comparable options for similar off-line LED current mode controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ICE2QS03G	650 V integrated MOSFET; no propagation delay compensation; fixed blanking time.	Limited to ≤230 V_AC input; requires external startup resistor; lower current accuracy (±8%) over temperature.	Preferred for cost-sensitive indoor lamps with narrow input range and relaxed regulation specs.
ILC8023Z	Same PG-DIP-7 footprint; identical pinout; 800 V CoolMOS™; but lacks FLP and extended blanking mode.	Supports same universal input and topology, but fails open-circuit LED detection; requires external FLP circuitry.	Selected when FLP is not required and legacy design reuse is prioritized over protection completeness.

Compared with ICE2QS03G and ILC8023Z, the ICLS8023Z uniquely combines 800 V integration, propagation delay compensation, and floating load protection-enabling single-chip, safety-certifiable LED drivers for outdoor and retrofit applications where reliability and regulatory compliance are critical.

FAQ

Does ICLS8023Z require an external startup resistor?

No. The ICLS8023Z integrates a dedicated startup cell that draws initial current directly from the DRAIN pin, eliminating the need for external high-voltage startup resistors. This reduces power loss during startup and improves system efficiency by up to 0.8% at full load compared to discrete solutions.

What is the maximum output power achievable with ICLS8023Z?

At 230 V_AC input and 85°C ambient, the ICLS8023Z supports up to 25 W continuous output power in flyback topology with proper heatsinking and transformer design. Derating to 18 W is recommended for operation at 110 V_AC and 85°C to maintain SOA compliance.

Can ICLS8023Z be used in constant-voltage LED drivers?

No. The ICLS8023Z is strictly a constant-current controller optimized for LED string regulation. Its FB and CS inputs are configured for primary-side current sensing and regulation; it does not support voltage feedback loop configuration or CV mode operation.

Is PG-DIP-7 the only package option for ICLS8023Z?

Yes. According to Infineon's official datasheet (Version 1.0, 2011-09-26), the ICLS8023Z is exclusively offered in the PG-DIP-7 package. No SOIC, DSO, or surface-mount variants were released for this specific part number.
