R1290K102A-E2

Overview

The R1290K102A-E2 is a triple output DCDC converter designed for LCD and CCD applications. It operates within an ambient temperature range of -40°C to 95°C (TA) and supports surface mount installation. The device is housed in a 24-WFQFN exposed pad package, specifically QFN0404-24. It provides up to 20V output voltage capability. This component belongs to the R1290K series and functions as an LCD driver power supply solution.

Feature Summary

• Triple output DCDC conversion architecture
• Integrated LCD driver power management
• Surface mount compatible design

Applications

• TFT LCD converters
• CCD system power supplies
• LCD display driver circuits

Procurement Notes

Verify the exact package designation QFN0404-24 against schematic footprints. Confirm operating temperature limits of -40°C to 95°C match system requirements. Ensure input voltage specifications align with source rails. Check RoHS compliance status if required by assembly standards. Validate pinout compatibility during PCB layout finalization.

Selection Notes

Select this component when triple isolated or non-isolated outputs are needed for LCD/CCD biasing. Consider the 24-pin QFN footprint for space-constrained designs. Evaluate thermal performance given the exposed pad requirement. Compare efficiency metrics against single-output alternatives if multiple rails are unnecessary. Verify availability in tape and reel packaging for automated assembly.
