MIC4811YMM

LED Driver IC Overview

The MIC4811YMM is a high-efficiency linear White LED driver designed to drive up to six high-current WLEDs while maintaining constant current in each channel. It features PWM dimming capability and operates within a supply voltage range of 3.5V to 5.5V. The device delivers an output current of 50mA per channel and is housed in a 10-pin MSOP package. It supports an operating temperature range from -40°C to 125°C TJ.

LED Driver IC Feature Summary

• High-efficiency linear topology for driving multiple white LEDs
• Constant current regulation across up to six channels
• Supports PWM dimming control for brightness adjustment

LED Driver IC Applications

• Signage lighting systems
• White LED backlighting applications
• Portable electronic devices requiring multi-channel LED drivers

LED Driver IC Procurement Notes

Verify the specific suffix 'YMM' corresponds to the tube packaging variant when ordering. Confirm RoHS compliance status with the supplier as required by project specifications. Ensure the 10-MSOP footprint matches the PCB design constraints. Validate that the 50mA output current meets the target LED forward current requirements without external components.

LED Driver IC Selection Notes

Select this component when a linear solution is preferred for low-noise applications involving up to six white LEDs. Consider the 50mA per channel limit and the 3.5V to 5.5V input voltage window. The MSOP-10 package is suitable for space-constrained designs. Evaluate thermal dissipation capabilities given the linear topology at higher input-to-output voltage differentials.
