• High-voltage gamma reference generation for liquid crystal displays

Procurement Notes

Verify component authenticity through authorized channels as the part status is listed as obsolete. Confirm package integrity and pin alignment for the 48-WFQFN form factor. Ensure compatibility with existing PCB footprints and thermal requirements given the exposed pad design. Cross-reference datasheet revisions to confirm electrical specifications match system requirements before procurement.

Selection Notes

Select this component for systems requiring integrated VCOM amplification and gamma references within a single power management solution. Evaluate the 200mA output current against load demands and verify the 8V-16.5V input range matches available power rails. Consider the 48-pin TQFN footprint for space-constrained designs and ensure thermal dissipation strategies align with the exposed pad mounting type.

Part Context

This part belongs to Maxim Integrated's family of display driver power management solutions. It combines power sequencing functions with analog signal conditioning components essential for high-quality LCD video rendering. The integration reduces bill-of-materials count by consolidating multiple discrete power and amplifier stages into a single monolithic IC.
