Product details
Overview
ICL8800XUMA1 from Infineon is a voltage-mode quasi-resonant flyback controller for constant-voltage (CV) output, supporting both secondary-side regulation (SSR) and primary-side regulation (PSR) topologies. It delivers high power factor (>0.9 at full load), low THD (<10% across 20–100% load), universal AC input (90–300 VAC, 45–66 Hz), and operates in QRM/valley-switching DCM with adjustable on-time mapping and maximum on-time limiting - enabling robust 125 W battery charging and LED driver designs.
For engineers reviewing the ICL8800XUMA1 datasheet, ICL8800XUMA1 pinout, ICL8800XUMA1 application, or ICL8800XUMA1 equivalent, key selection considerations include its SSR/PSR dual-mode capability, integrated brown-in/brown-out protection, valley-sensing ZCD interface, THD correction via TD pin, and compatibility with CoolMOS™ P7 MOSFETs for light-load efficiency optimization.
Technical Context
The ICL8800 implements voltage-mode control with digital state-machine-driven pulse generation, using ZCD sensing for valley detection and VIN-based input voltage monitoring for adaptive power limitation and protection triggering. Its THD correction circuitry adjusts turn-on delay dynamically to maintain high PF across line/load variations.
It supports three operating modes: QRM at medium-to-heavy loads, valley-switching DCM at light loads, and soft-start with reduced gate drive voltage. The CS pin provides primary-side overcurrent protection with blanking time, while VS enables feedback-based CV regulation without optocoupler dependency in SSR configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Topology Support | Flyback CV with SSR or PSR operation - eliminates need for optocoupler in SSR mode, reduces BOM count in PSR mode. |
| Input Voltage Range | 90–300 VAC (45–66 Hz) or DC - enables global mains compatibility and DC-powered emergency lighting use. |
| Power Factor | >0.9 at full load, >0.7 at 20% load - meets IEC 61000-3-2 Class C for lighting and appliance applications. |
| THD | <10% across 20–100% load - ensures compliance with harmonic current emission limits without external PFC stage. |
| Protection Features | OTP, OVP (flyback output), OCP (primary side), brown-in/out, VCC OVP, open-loop, input OVP - enables fully self-protected offline SMPS design. |
| Operating Modes | QRM + valley-switching DCM - improves efficiency and EMI by switching at MOSFET drain voltage minima. |
| Max Switching Frequency | Adjustable up to 130 kHz - balances transformer size, core loss, and EMI filter requirements. |
Pinout & Package
ICL8800XUMA1 is housed in a PG-DSO-8 (SOIC-8) package with exposed thermal pad, optimized for high-voltage isolation and thermal dissipation in offline flyback converters.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ZCD | Zero-crossing detection input | Connects to auxiliary winding via series resistor to enable valley-switching timing; resistor value sets on-time mapping and max on-time. |
| VS | Voltage sense feedback | Measures isolated output voltage via resistive divider in SSR-CV mode; enables optocoupler-free regulation. |
| VIN | Input voltage detection | Monitors rectified input for brown-in/out, input OVP, and power limitation; enables jitter function in ICL8820 (not active in ICL8800). |
| TD | THD correction and start-up control | External resistor to ground configures THD gain and zero-crossing delay; internal pull-up drives external VCC charge circuit during start-up. |
| CS | Current sense and OVP | Detects primary MOSFET current for OCP; same pin sets flyback output OVP threshold via shunt resistor ratio. |
| GD | Gate driver output | Drives CoolMOS™ gate directly; reduced voltage during start-up lowers required VCC capacitance for faster turn-on. |
| GND | Signal and power ground | Common reference for VCC supply, GD output, and all sense inputs; must be low-inductance connection to minimize noise coupling. |
| VCC | Supply voltage input | Accepts 11.5–25 V DC; internal UVLO (10.5 V) and OVP (27 V) protect against supply faults. |
Key Features
| Feature | Design Value |
|---|---|
| Quasi-resonant + valley-switching DCM | Reduces switching losses and EMI by synchronizing MOSFET turn-on with drain voltage minima across load range. |
| Adjustable on-time mapping | Enables precise control of peak current and output power via ZCD resistor - critical for stable CV regulation under varying line conditions. |
| Integrated brown-in/brown-out protection | Prevents erratic operation during unstable AC mains by disabling switching below 85 VAC or above 310 VAC (typical thresholds). |
| Soft-start with reduced GD voltage | Limits inrush current and stress on startup components; allows smaller VCC capacitor (e.g., 4.7 µF instead of 10 µF) for faster system wake-up. |
| Comprehensive fault protection set | Single-chip solution eliminates need for discrete protection ICs - reduces board space and improves reliability in cost-sensitive lighting/appliance designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flyback controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICL8810XUMA1 | Includes burst mode for <150 mW standby power; identical pinout and SSR/PSR support. | Required for energy-efficient smart lighting with strict ERP Tier 2 standby limits. | Select ICL8810 if standby power <200 mW is mandatory; otherwise ICL8800 offers lower system cost. |
| UCC28632DR | Fixed-frequency DCM flyback controller; no QRM/valley switching; lower PF (~0.85) and higher THD (~15%) at light load. | Suitable for non-regulated or low-cost LED drivers where harmonic compliance is not enforced. | Choose UCC28632 only when BOM cost is prioritized over PF/THD performance and regulatory certification. |

FAQ
Does ICL8800XUMA1 support primary-side regulation (PSR) without an optocoupler?
Yes - ICL8800XUMA1 supports PSR-CV operation using the VS pin to sense reflected output voltage via the transformer auxiliary winding. This eliminates the optocoupler and TL431, reducing component count and improving long-term stability in LED driver and charger applications.
What is the purpose of the TD pin, and how is it configured?
TD pin sets THD correction gain and zero-crossing turn-on delay via an external resistor to GND. A typical 220 kΩ resistor achieves optimal THD compensation across line/load; its internal pull-up also enables control of external VCC pre-charge circuits during startup.
Can ICL8800XUMA1 operate with DC input, such as from a battery or PoE-derived rail?
Yes - it accepts DC input from 127 VDC to 424 VDC (equivalent to 90–300 VAC RMS), enabling use in DC-powered emergency lighting, telecom, and industrial backup systems. Input voltage detection via VIN pin remains functional for protection and power limiting.
How does the ZCD pin enable quasi-resonant operation?
ZCD monitors the auxiliary winding voltage to detect MOSFET drain voltage valleys. By adjusting the series resistor between ZCD and the winding, designers set the on-time mapping and maximum on-time - ensuring switching occurs at minimum voltage points for lowest EMI and conduction loss.
