Overview
The ICL8810XUMA1 is an AC-DC LED driver IC from Infineon Technologies, designed for constant-voltage (CV) output applications. It utilizes a voltage-mode quasi-resonant flyback topology with support for both secondary-side regulation (SSR) and primary-side regulation (PSR). The device operates within an input voltage range of 8 V to 24 V and delivers an output current of up to 250 mA. It features an adjustable output voltage and operates at frequencies between 20 kHz and 150 kHz. The component is housed in a PG-DSO-8 package and functions reliably across a temperature range of -40°C to +125°C.
Feature Summary
- Supports both secondary-side regulation (SSR) and primary-side regulation (PSR) for flexible design options
- Integrates voltage-mode quasi-resonant flyback control for high efficiency
- Includes soft-start functionality to manage inrush currents
Applications
- LED lighting systems requiring constant voltage outputs
- Offline AC-DC power supplies for general illumination
- Smart LED lighting applications compatible with IoT integration
Procurement Notes
Verify the specific ordering suffix and packaging configuration when sourcing. Confirm that the component meets required RoHS compliance standards for your region. Ensure the supplier provides valid traceability documentation. Check for any recent lifecycle status updates or obsolescence notices directly from Infineon Technologies before finalizing procurement decisions.
Selection Notes
Select this component for designs requiring a single-output flyback converter with integrated regulation capabilities. It is suitable for applications needing high power factor correction and low total harmonic distortion. Consider the PG-DSO-8 package constraints for PCB layout. Evaluate whether SSR or PSR modes better suit the specific cost and performance requirements of the target LED lighting system.
Part Context
The ICL8810XUMA1 belongs to Infineon's ICL88xx series of AC-DC LED driver ICs. This family focuses on delivering excellent power quality and high efficiency for LED lighting applications. The series supports dimming levels down to 0.1% and aims to minimize system costs by reducing external component counts. It complements other controllers like the ICL8800 and ICL8820 within the same product line.
Replacement Considerations
The ICL8800XUMA1 is a related part within the same ICL88xx series offering similar flyback controller functionality. Verify pin compatibility and electrical specifications before substitution. Consult official Infineon documentation for detailed cross-reference data and application note recommendations regarding equivalent components.
