MIC4827YMM

Overview

The MIC4827YMM is a single-output electroluminescent (EL) lamp driver IC manufactured by Microchip Technology. It utilizes a boost topology to generate high-voltage AC outputs from low-voltage DC inputs, supporting supply voltages between 1.8 V and 5.5 V. The device operates at frequencies ranging from 60 Hz to 1 kHz and can produce output voltages up to 90 V. Packaged in an 8-MSOP surface-mount case, it functions within a temperature range of -40°C to +85°C with a maximum power dissipation of 200 mW.

Feature Summary

• Integrated boost converter topology designed specifically for driving electroluminescent panels
• Operates on low input voltage ranges suitable for battery-powered portable applications
• Supports variable frequency control for EL panel brightness adjustment

Applications

• Backlighting for liquid crystal displays (LCDs)
• Instrument cluster illumination in automotive dashboards
• Control panel lighting in industrial equipment

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm packaging type, as the base part number may correspond to tube packaging while tape-and-reel variants carry distinct suffixes. Confirm RoHS compliance status and moisture sensitivity level requirements prior to ordering to ensure compatibility with assembly processes.

Selection Notes

Select this component when designing circuits requiring efficient drive for EL lamps using low-voltage sources. Ensure the application demands a single-channel boost driver with frequency modulation capabilities. Verify that the required output voltage and operating frequency align with the electrical specifications of the target EL panel.

Part Context

This device belongs to the MIC4827 series of LED and EL lighting drivers. It shares functional similarities with the MIC4826 but offers specific electrical characteristics tailored for different load requirements. The series provides compact solutions for backlighting needs in consumer electronics and automotive interfaces.

Replacement Considerations

The MIC4826YMM is a related variant within the same product family. Cross-reference datasheets to verify if pinout compatibility and specific electrical parameters meet the design requirements before substitution.
