SC5012MLTRT

Overview

The SC5012MLTRT is a high-efficiency, four-channel step-up (Boost) HB LED driver designed for backlight applications. It features an input voltage range of 4.75V to 45V and supports output voltages up to 65V. Each channel provides a programmable current sink of up to 150mA with ±1% current matching accuracy. The device includes I2C control, phase-shifted PWM dimming with user-selectable resolution, and external frequency synchronization capabilities.

Feature Summary

• Four independent high-precision current sinks supporting up to 150mA per channel
• Integrated I2C interface for digital device control and status monitoring
• Supports analog and PWM dimming with string-by-string phase shifting
• Includes comprehensive protection features such as open/short LED detection and over-temperature shutdown

Applications

• Medium-sized LCD panel backlighting
• Automotive navigation and information displays
• LCD monitors

Procurement Notes

Verify the specific suffix 'MLTRT' against official Semtech documentation to confirm package type and reel specifications. Ensure compatibility with the required operating temperature range and I2C address settings for the target design. Confirm availability of the AEC-Q100 qualified version if automotive standards are mandatory.

Selection Notes

Select this component for designs requiring precise multi-channel LED current regulation via digital interface. Consider the wide input voltage range and boost topology for battery-powered or variable supply systems. Evaluate the need for phase-shifted dimming to reduce EMI in dense display arrays.

Part Context

This part belongs to the SC501 series of LED drivers from Semtech Corporation. It is specifically engineered for high-efficiency power management in display backlighting applications, offering a compact solution with integrated control logic and protection mechanisms within a small footprint package.

Replacement Considerations

Consult official Semtech substitution guides for verified alternatives. Generic replacements may not match the specific I2C command set or phase-shifting capabilities.
