• Supports PWM dimming control for brightness adjustment
• Integrated boost converter topology for efficient power management

Applications

• LCD backlighting for mobile devices
• Portable electronic display systems
• White LED driver circuits in consumer electronics

Procurement Notes

Verify the specific suffix (LF-P) against the manufacturer's current datasheet to confirm lead-free status and tape-and-reel packaging specifications. Ensure the ordering part number matches the exact electrical parameters required for your design, as suffixes may indicate variations in packaging or material compliance that do not alter the core functionality.

Selection Notes

Select this component when designing low-current backlighting solutions requiring four independent channels. It is suitable for systems operating between 3 V and 25 V where precise current regulation at the microampere level is necessary. Consider the QFN-16 package size and thermal performance relative to your PCB layout constraints and ambient operating temperatures.
