Procurement Notes

Verify component authenticity through authorized Analog Devices or Maxim Integrated distributors. Confirm the specific suffix matches the required variant. Check for end-of-life status or obsolescence notices prior to procurement. Ensure compatibility with existing PCB footprints and thermal requirements. Validate RoHS compliance documentation for regulatory adherence.

Selection Notes

Select this component when designing power supplies for TFT-LCD displays requiring integrated gamma and VCOM generation. Consider the 8 V to 16.5 V input range and 60 mA output capability against system load requirements. Evaluate the 48-TQFN package size for space-constrained layouts. Assess thermal dissipation needs given the 3.0769 W power rating. Compare against alternative PMICs if higher output currents or different voltage ranges are necessary.
