• Integrated dimming functionality allowing for adjustable backlight intensity
• Operates at standard CCFL frequencies ranging from 40kHz to 100kHz

Applications

• Automotive display backlighting systems
• Cold cathode fluorescent lamp driving circuits
• Dashboard and instrument panel illumination control

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm RoHS compliance and REACH material declarations prior to integration. Check for obsolescence notices as the part may be discontinued or subject to restricted supply conditions. Ensure packaging specifications match design requirements for surface mount assembly processes.

Selection Notes

Select this component for designs requiring dedicated dual-channel CCFL management in automotive environments. Consider the 28-TSSOP footprint and thermal characteristics for PCB layout. Evaluate the 4.75V to 5.25V supply requirement against system power rails. Assess the -40°C to +105°C operating range against environmental constraints. Verify compatibility with existing dimming control interfaces before finalizing the bill of materials.
