Overview
The MSL1064AW-R is a six-channel LED lighting driver IC manufactured by Microchip Technology. It operates as a DC-DC step-up (boost) regulator with an input voltage range of 4.75 V to 36 V and supports output voltages up to 48 V. The device provides 30 mA per channel and features digital control with PWM dimming capabilities at a switching frequency of 1.1 MHz. It is housed in a 24-pin QFN package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates a six-channel boost topology for driving multiple LED strings from a single component.
- Supports both analog and pulse-width modulation (PWM) dimming methods for precise brightness regulation.
- Includes internal digital control logic to manage current regulation and dimming sequences.
Applications
- General illumination systems requiring multi-string LED drivers
- Backlighting applications for displays
- Automotive interior lighting modules
Procurement Notes
Verify the specific suffix 'R' indicates the reel packaging configuration, as this affects handling and storage requirements. Confirm that the component status is End-of-Life (EOL) or Not Recommended for New Designs (NRND) before finalizing procurement plans. Ensure compatibility with existing PCB footprints for the 24-TQFN package. Check RoHS compliance documentation for environmental regulations relevant to your region.
Selection Notes
Select this component when a compact solution for driving up to six independent LED strings is required. It is suitable for designs needing high efficiency via boost topology and flexible dimming options. Consider the 30 mA output limit per channel when sizing the LED load. Verify that the system input voltage falls within the 4.75 V to 36 V operating range.
Part Context
This part belongs to the MSL106x series of LED drivers from Microchip Technology. These devices are designed for power management applications, specifically focusing on efficient LED lighting control. The series typically integrates power switches and control logic to simplify design complexity compared to discrete solutions.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult Microchip Technology directly for recommended alternatives or cross-reference guides due to the component's end-of-life status.
