R1290K003A-E2

Overview

The R1290K003A-E2 is a triple output DC-DC converter designed for LCD and CCD applications, manufactured by Nisshinbo Micro Devices. It integrates three independent voltage regulators within a single QFN0404-24 package to simplify power supply design for display drivers. The device operates as a switching regulator, providing stable outputs required for panel biasing without external inductors or complex transformer circuits. This integration reduces component count and board space while maintaining efficiency for portable electronic devices requiring compact power solutions.

Feature Summary

• Integrates three independent output channels for simultaneous LCD/CCD bias generation
• Utilizes a compact QFN0404-24 surface-mount package to minimize footprint
• Designed specifically for driving liquid crystal displays and charge-coupled devices

Applications

• Liquid Crystal Display (LCD) driver power supplies
• Charge-Coupled Device (CCD) sensor bias circuits
• Portable electronic devices with integrated display modules

Procurement Notes

Verify the manufacturer designation carefully, as some distributor listings may incorrectly attribute this part to Murata Electronics due to historical corporate relationships or data entry errors. Confirm the specific suffix E2 matches the required RoHS compliance and packaging format. Cross-reference the Mouser number 848-R1290K101A-E2 if available documentation is ambiguous, but ensure the base part number R1290K003A aligns with the intended electrical specifications before procurement.

Selection Notes

Select this component when a triple-output power solution is required for display technologies. Ensure the input voltage range and output current requirements of the target LCD or CCD match the internal regulator capabilities. The QFN0404-24 package necessitates appropriate PCB thermal management and soldering profiles suitable for fine-pitch surface mount technology. Verify compatibility with the system's ground reference and control signal levels.

Part Context

This part belongs to the R1290K series of LCD driver ICs from Nisshinbo Micro Devices. The series focuses on integrating multiple power rails into a single chip to support complex display interfaces. The R1290K003A variant specifically addresses the need for three distinct voltage levels, commonly used for VGH, VGL, and AVDD in TFT-LCD panels. It represents a consolidation of discrete power management components into a unified semiconductor solution.
