R1290K001A-E2

Overview

The R1290K001A-E2 is a triple output DC-DC converter specifically designed for LCD and CCD applications, manufactured by Nisshinbo Micro Devices. It integrates three distinct voltage outputs to support complex display driving requirements within a single compact package. The device utilizes a QFN0404-24 surface-mount package to facilitate efficient PCB layout and thermal management in space-constrained electronic designs.

Feature Summary

• Integrates three independent output channels for simultaneous power supply generation
• Optimized architecture tailored for LCD and CCD driver circuitry
• Compact QFN0404-24 surface mount packaging for space-efficient integration

Applications

• Liquid Crystal Display (LCD) driver power systems
• Charge-Coupled Device (CCD) sensor power supplies
• Portable imaging equipment requiring multi-rail power distribution

Procurement Notes

Verify the manufacturer designation carefully, as some distributor listings may incorrectly attribute this part to Murata Electronics despite Nisshinbo being the primary producer. Confirm the specific suffix E2 matches your board design requirements. Ensure compatibility with the QFN0404-24 footprint during procurement planning.

Selection Notes

Select this component when a single-chip solution for triple-output power generation is required for display drivers. It eliminates the need for multiple discrete converters, reducing component count and board area. Verify that the integrated output voltages meet the specific biasing needs of the target LCD or CCD module without external adjustment.

Part Context

This part belongs to the R1290K series of specialized power management ICs focused on display technologies. Unlike general-purpose buck converters, this series addresses the specific transient and stability requirements of image sensors and liquid crystal panels, providing a consolidated power solution for visual processing hardware.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires consulting official Nisshinbo Micro Devices replacement guides or verifying pin-compatible alternatives through direct manufacturer datasheet comparison.
