MSL1061AV

Overview

The MSL1061AV is a six-string LED driver IC featuring a digitally compensated 1.1MHz boost regulator with an integrated 48V switch. It operates on an input voltage range of 4.75V to 36V and supports both analog and PWM dimming. The device ensures high current balance accuracy of ±1.5% across its six channels, utilizing a 28-pin TQFN package for surface mount installation.

Feature Summary

• Integrates a 1.1MHz current mode PWM boost regulator with a 48V internal switch
• Provides digitally compensated current balance for consistent multi-string performance
• Supports flexible control via combined analog and pulse-width modulation dimming methods

Applications

• High-brightness LED lighting systems
• LED backlighting modules
• Automotive illumination circuits

Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors due to the presence of counterfeit risks in the market. Confirm the specific suffix 'AV' matches the required package and temperature grade specifications before finalizing orders. Ensure supply chain stability as availability may vary by region.

Selection Notes

Select this component for designs requiring precise current regulation across multiple LED strings without external balancing resistors. The wide input voltage range accommodates various power sources, while the high switching frequency allows for compact passive component selection. Evaluate thermal management requirements for the 28-TQFN package under maximum load conditions.

Part Context

This part belongs to the MSL106x family of LED drivers from Microchip Technology, designed for efficient multi-channel LED control. It shares architectural similarities with models like the MSL1060 but offers specific voltage and channel configurations tailored for distinct lighting applications.

Replacement Considerations
