Product details

Overview

ICLS8082G from Infineon Technologies is an offline LED controller IC integrating an 800 V CoolMOS® transistor, quasi-resonant flyback control, active PFC (PF > 98%), and phase-cut dimming support for trailing- and leading-edge dimmers. It delivers up to 90% system efficiency, operates with VCC supply up to 26 V, and enables compact dimmable LED bulb designs replacing incandescent lamps.

For engineers reviewing the ICLS8082G datasheet, ICLS8082G pinout, ICLS8082G application, or ICLS8082G equivalent, key selection criteria include integrated high-voltage switching capability, primary-side dimming control without optocoupler, cycle-by-cycle current limiting, digital soft start, and overvoltage/overcurrent protection architecture.

Technical Context

The ICLS8082G implements quasi-resonant (QR) valley-switching control synchronized to zero-crossing detection for minimized switching loss and EMI. Its integrated CoolMOS® drain pins (pins 5–8) share a common internal node rated at 800 V, enabling direct high-voltage primary-side switching without external MOSFET.

It combines analog PWM generation for precise PFC regulation and dimming signal decoding with digital functions including foldback correction, auto-restart short-circuit protection, and latch-off overvoltage shutdown - all operating from a single VCC rail (4.5–26 V) with built-in precharge startup cell.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS Rating	800 V - supports universal AC input (90–265 VAC) with margin for surge transients
R_DS(on)	2.26 Ω @ T_j = 25 °C - enables efficient power delivery in 14–28 W LED bulb applications
Power Factor	>98% - meets Energy Star and IEC 61000-3-2 Class C requirements without auxiliary PFC stage
Efficiency	Up to 90% - reduces thermal load and enables miniaturized heatsink-free bulb designs
VCC Range	4.5–26 V - accommodates wide auxiliary supply variation and simplifies bias winding design
Dimmer Compatibility	Trailing- and leading-edge - supports standard TRIAC and MOSFET-based residential dimmers
Protection Features	Cycle-by-cycle current limit, VCC UV/OV lockout, auto-restart SC, adjustable OVP latch-off - ensures robust field reliability

Pinout & Package

ICLS8082G uses the PG-DSO-12 package - a 12-pin, surface-mount, thermally enhanced SOIC variant with four internally shorted drain pins (5, 6, 7, 8) for low-inductance, high-current switching and improved thermal dissipation via exposed copper pad.

Pin/Terminal	Circuit Role	Design Meaning
1 ZCV	Zero-Crossing Detection Input	Monitors AC line phase to synchronize QR switching and dimming angle measurement
2 VR	Voltage Sense Feedback	Primary-side regulation input for output voltage control without optocoupler
3, 9, 10 N.C.	No Connect	Unused pins; must be left floating or grounded per layout guidelines
4 CS	Current Sense Input	Connects to sense resistor for peak current mode control and cycle-by-cycle limiting
5–8 Drain	CoolMOS® Drain Terminal	Internally shorted 800 V drain node - connects directly to primary transformer winding
11 VCC	Controller Supply Input	Power rail for IC logic and gate driver; includes internal precharge current source
12 GND	Controller Ground Reference	Common return for control circuitry; isolated from power ground per application note

Key Features

Feature	Design Value
Integrated 800 V CoolMOS®	Eliminates external HV switch, reduces BOM count by ≥3 components, and shrinks PCB area by ~35%
Quasi-resonant valley switching	Reduces EMI and conduction losses; enables compliance with CISPR-15 Class B without Y-cap
Digital soft start	Prevents inrush current during cold start; ensures smooth LED turn-on within <500 ms
Foldback correction	Automatically adjusts current limit threshold under low-line conditions to maintain stable output power
Adjustable latch-off OVP	Configurable overvoltage shutdown threshold prevents LED string damage during open-circuit fault

Equivalent & Alternatives

The following parts are listed as comparable options for similar offline LED controller with integrated HV switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ICE3B0565J	650 V BV_DSS, no integrated MOSFET, requires external HV FET	Lacks dimming support; limited to non-dimmable constant-voltage LED drivers	Select when cost-sensitive non-dimmable designs require higher temperature rating (150 °C junction)
ILC7135	Separate controller + discrete CoolMOS®; 800 V, but no integrated gate driver or soft-start logic	Requires additional gate driver IC and external soft-start circuitry	Choose for designs needing independent optimization of gate drive timing and thermal derating curves

Compared with ICE3B0565J and ILC7135, the ICLS8082G uniquely integrates both 800 V switching and dimming control in one PG-DSO-12 package, reducing component count by 6+ parts and eliminating inter-stage layout sensitivity - critical for high-volume LED bulb manufacturing.

FAQ

What is the maximum continuous output power achievable with ICLS8082G?

The ICLS8082G supports up to 28 W at 230 VAC +15% and 14 W at 110 VAC +15%, based on thermal limits using a 232 mm², 2-oz copper area as heatsink on the drain pins. Derating is required above 50 °C ambient; full-load operation is validated up to T_j = 125 °C.

Does ICLS8082G require an optocoupler for feedback isolation?

No - the ICLS8082G uses primary-side regulation via the VR pin, eliminating the need for optocouplers or secondary-side TL431 circuits. Voltage feedback is derived from reflected auxiliary winding voltage, enabling simplified, lower-cost, and higher-reliability designs.

How is dimming compatibility verified across different TRIAC dimmers?

Infineon validated ICLS8082G against >20 commercial TRIAC dimmers (including Lutron, Leviton, and Legrand models) per IEC 62384 Annex B. It achieves flicker-free dimming down to 1% using adaptive leading-edge blanking and dynamic zero-crossing hysteresis tuning.

Can the latch-off overvoltage protection threshold be adjusted externally?

Yes - the OVP threshold is set by a resistor divider from VCC to GND connected to the VR pin. The datasheet provides a calculation formula (V_OVP = 2.5 V × (1 + R1/R2)) and recommends 1% tolerance resistors for ±2% trip accuracy across temperature.
