MIC2287-24YML

LED Driver IC Overview

The MIC2287-24YML is a 1.2MHz PWM boost-switching regulator optimized for constant-current white LED driver applications. It features an internal switch capable of delivering up to 750mA per channel and supports a maximum output voltage of 34V, allowing it to drive strings of up to eight series-connected white LEDs. The device operates with a supply voltage range of 2.5V to 10V and includes a fixed 24V overvoltage protection (OVP) threshold. Packaged in an 8-pin MLF® (2x2mm) surface-mount case, it supports analog and PWM dimming functions.

LED Driver IC Feature Summary

• Integrated high-current boost switching regulator with internal power switch
• Fixed 24V overvoltage protection (OVP) for enhanced circuit safety
• Supports both analog and pulse width modulation (PWM) dimming control
• Optimized for driving long strings of white LEDs in series

LED Driver IC Applications

• Backlighting for mobile devices and portable electronics
• Camera flash lighting systems
• General white LED illumination circuits

LED Driver IC Procurement Notes

Verify the specific suffix 'YML' confirms the 8-MLF package and 24V OVP variant. Confirm RoHS compliance status as Micrel was acquired by Microchip Technology; documentation may reflect either brand name. Ensure the required tape-and-reel quantity matches your production needs, as packaging options vary between cut tape and full reels.

LED Driver IC Selection Notes

Select this component when a fixed 24V output limit is required for LED string protection. It is suitable for single-output designs needing up to 750mA switch current. Consider alternative MIC2287 variants if different OVP thresholds or package types are needed. Verify input voltage compatibility within the 2.5V to 10V range for your specific power source.

LED Driver IC Part Context

This part belongs to the MIC2287 family of LED drivers from Micrel (now Microchip). The family shares a common 1.2MHz boost topology but differs primarily in their overvoltage protection thresholds and package configurations. The MIC2287-24YML specifically denotes the version with 24V OVP housed in the compact 8-MLF footprint.

LED Driver IC Replacement Considerations

MIC2287-15YML-TR: Identical topology and package but features a 15V OVP threshold instead of 24V. Use only if the lower voltage limit meets application requirements.

LED Driver IC FAQ

What is the maximum output voltage capability of the MIC2287-24YML?

The device can generate a maximum output voltage of 34V, although it includes a fixed 24V overvoltage protection threshold.

Does the MIC2287-24YML support external dimming?

Yes, it supports both analog and pulse width modulation (PWM) dimming methods for brightness control.
