MIC3203-1YM-TR

LED Driver IC Overview

The MIC3203-1YM-TR is a high-brightness LED driver controller from Microchip Technology, utilizing a buck topology. It operates within an input voltage range of 4.5 V to 42 V and delivers a maximum output current of 1 A. The device functions at a switching frequency of 1.5 MHz and includes a high-side current sense feature for precise regulation. It supports PWM dimming and is housed in an 8-pin SOIC package. The component is rated for operation between -40°C and +125°C.

LED Driver IC Feature Summary

• Integrates high-side current sensing for accurate LED current regulation without external shunt resistors.
• Supports PWM dimming control for adjustable brightness levels in lighting applications.
• Features a fixed 1.5 MHz switching frequency to minimize external passive component size.

LED Driver IC Applications

• High-brightness LED lighting systems
• Automotive exterior lighting modules
• General-purpose constant current LED drivers

LED Driver IC Procurement Notes

Verify the specific suffix (e.g., TR) indicates tape-and-reel packaging if required by assembly equipment. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed during storage and installation due to moisture sensitivity classification.

LED Driver IC Selection Notes

Select this component when a compact buck converter solution is needed for single-channel LED strings. The wide input voltage range accommodates various supply sources, including automotive batteries. Consider the 1 A current limit and thermal performance in the SOIC-8 package for power dissipation requirements.

LED Driver IC Part Context

This part belongs to the MIC3203 series of LED driver controllers. It is functionally similar to the MIC3203YM but differs in packaging format, with the -TR suffix denoting tape-and-reel delivery suitable for automated surface-mount assembly processes.

LED Driver IC Replacement Considerations

The MIC3203YM is a non-tape-and-reel variant of the same functional device. Verify pin compatibility and thermal characteristics when substituting between reel and tube packages.
