MSL2161DQ-R

Overview

The MSL2161DQ-R is a linear LED driver IC from Microchip Technology’s Adaptive SourcePower series, designed for white and RGB LED applications. It features 16 independent output channels with PWM dimming capability. The device operates on a 12 V supply voltage and supports an operating temperature range of -40°C to +85°C. Packaged in a 64-TQFN (9x9 mm) exposed pad format, it delivers up to 30 mA per channel with a power dissipation of 2.1 W. This automotive-grade component is currently obsolete.

Feature Summary

Supports 16-channel linear current regulation with integrated PWM dimming
Optimized for white and RGB LED string configurations
Automotive-grade reliability with wide thermal operating range

Applications

White LED backlighting systems
RGB LED lighting modules
Automotive interior illumination

Procurement Notes

Verify component obsolescence status before integration. Confirm package compatibility with existing PCB footprints. Check for available last-time buy options or authorized distributor clearance. Validate RoHS compliance documentation. Ensure design-in alternatives are identified due to discontinued manufacturing status.

Selection Notes

Select this part for designs requiring high-channel-count linear LED control. Verify input voltage stability at 12 V. Consider thermal management requirements given the 2.1 W dissipation limit. Evaluate pinout compatibility if replacing legacy drivers. Confirm automotive qualification meets specific project standards.

Part Context

Part of the Adaptive SourcePower family, the MSL2161DQ-R targets multi-string LED architectures. It integrates precise current regulation without external sense resistors for simplified design. The TQFN package facilitates surface-mount assembly in compact lighting enclosures.

Replacement Considerations

No direct public substitute part numbers are confirmed. Designers should evaluate newer Microchip LED driver families or third-party equivalents with matching channel counts and thermal profiles.
