MIC3202YME-TR

LED Driver IC Overview

The MIC3202YME-TR is a hysteretic step-down, constant-current High-Brightness LED driver IC manufactured by Microchip Technology. It operates with an input voltage range up to 37V and delivers a regulated output current of 1A. The device features high-side current sensing for precise control. It supports PWM dimming via an enable pin that requires a logic level of 2.0V or higher to activate the regulator. The component is housed in an 8-SOIC package with an exposed pad (SOIC-EP) and is designed for efficient power management in lighting applications.

LED Driver IC Feature Summary

• Hysteretic step-down topology for constant-current regulation
• High-side current sensing capability
• PWM dimming support through logic-level enable control

LED Driver IC Applications

• Interior and exterior lighting systems
• Architectural lighting installations
• Ambient lighting solutions
• LED bulbs and general illumination

LED Driver IC Procurement Notes

Verify the specific suffix '-TR' indicates tape-and-reel packaging when ordering. Confirm the 8-SOIC-EP package type matches your PCB footprint requirements. Ensure the design accommodates the 37V maximum input voltage and 1A output current limits. Check for RoHS compliance status as per manufacturer documentation before finalizing procurement specifications.

LED Driver IC Selection Notes

Select this component for applications requiring a single-channel constant-current solution with high-side sensing. It is suitable where hysteretic control offers sufficient stability without external compensation. Consider the 8-SOIC-EP package for thermal performance and space constraints. Verify compatibility with the required PWM dimming frequency and input voltage range of the target system.

LED Driver IC Part Context

The MIC3202 series includes variants such as MIC3202YME and MIC3202-1YME. The MIC3202-1YME shares similar electrical characteristics but may differ in packaging or trim options. The MIC3202YME-TR specifically denotes the tape-and-reel version of the standard MIC3202YME part. All variants fall under Microchip's LED driver portfolio for high-brightness LED applications.

LED Driver IC Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Evaluate alternatives based on matching hysteretic step-down topology, 1A constant current capability, and 8-SOIC-EP package compatibility. Verify equivalent high-side sensing and PWM dimming functionality before substitution.
