MIC3263YML-TR

LED Driver IC Overview

The MIC3263YML-TR is a six-channel Pulse Width Modulation (PWM) LED driver regulator designed for white WLED backlighting applications. It functions as a DC-DC step-up switching regulator optimized for high efficiency. The device integrates six constant-current outputs capable of driving up to 30mA per channel. It operates within an input voltage range of 2.7V to 6.4V and supports PWM dimming control. The component is housed in a 24-pin MLF package and is rated for operation between -40°C and +125°C.

LED Driver IC Feature Summary

• Six independent constant-current channels for uniform backlight illumination
• Integrated high-efficiency boost converter topology
• Supports external PWM dimming control signals
• Compact surface-mount packaging for space-constrained designs

LED Driver IC Applications

• Mobile phone LCD backlights
• Portable media player displays
• Digital camera flash units
• Tablet computer screens

LED Driver IC Procurement Notes

Verify the suffix TR indicates tape-and-reel packaging when ordering. Confirm the manufacturer is Microchip Technology, formerly Micrel. Ensure the part number matches MIC3263YML-TR exactly to avoid confusion with non-trimmed variants. Check datasheet revisions for any pinout or electrical specification updates before finalizing procurement.

LED Driver IC Selection Notes

Select this component for designs requiring multiple white LEDs driven from a single supply rail. It is suitable for battery-powered devices due to its high conversion efficiency. Consider the 24-MLF package size for PCB layout constraints. Verify that the required output current does not exceed the 30mA limit per channel.

LED Driver IC Part Context

This part belongs to the MIC3263 family of LED drivers. It is specifically engineered for portable electronics where power efficiency and small form factor are critical. The device replaces discrete solutions by integrating the boost controller and current regulators into a single IC.
