SC603IMLTRT

Overview

The SC603IMLTRT is a single-output LED driver IC manufactured by Semtech Corporation. It utilizes a switched capacitor (charge pump) topology to regulate current for LED applications. The device supports an input voltage range of 2.5 V to 6.5 V and provides a regulated output current of 200 mA. It operates at a switching frequency of 625 kHz. The component is housed in a 10-MLP (3x3 mm) surface-mount package.

Feature Summary

• Integrates a high-efficiency charge pump topology for DC-DC regulation
• Provides stable constant current output suitable for LED driving
• Supports dimming control capabilities

Applications

• General LED lighting systems
• Portable electronic device backlighting
• Industrial indicator lights

Procurement Notes

Verify the specific suffix LTRT indicates reel packaging when ordering. Confirm the MLP-10 package dimensions match your PCB footprint requirements. Ensure input voltage sources remain within the 2.5 V to 6.5 V operational limits to prevent damage. Check for RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component for designs requiring a compact, single-channel LED driver with integrated power switching. It is suitable where space constraints favor the small 3x3 mm MLP package over larger inductor-based solutions. Consider the 200 mA output limit when determining LED string configurations.

Part Context

This part belongs to Semtech's portfolio of power management integrated circuits (PMIC). It falls under the category of LED drivers and lighting controllers. The device is designed to replace discrete solution components, simplifying circuit design for low-to-medium power LED applications.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any replacement matches the 10-MLP package and 200 mA current rating. Verify compatibility with existing dimming control signals before substitution.
