Overview
The MSL2024-IN is an LED driver IC featuring two outputs, designed for AC/DC offline applications. It integrates a flyback and step-down (buck) converter topology with PWM dimming capability and supports up to 24-V QFN (4x4) packaging. The device drives external N-channel MOSFETs via a linear current controller for the main LED string. It provides ±3% current accuracy without ripple current.
Feature Summary
- Integrates flyback and buck converter topologies for AC/DC offline switching applications
- Supports PWM dimming functionality for precise light control
- Drives external N-channel MOSFETs using a linear current controller
- Delivers high current accuracy of ±3% with zero ripple current
Applications
- LED lighting systems requiring offline AC/DC power conversion
- Applications utilizing PWM dimming for brightness control
- Systems employing external N-channel MOSFETs for LED string driving
Procurement Notes
Verify the manufacturer designation, as Atmel was acquired by Microchip Technology. Confirm that the specific suffix '-IN' corresponds to the exact package and temperature grade required for your design. Ensure compatibility with the intended AC/DC offline topology and check if the external MOSFET selection aligns with the driver's output specifications.
Selection Notes
Select this component when a combined flyback and buck solution is needed for LED drivers in AC/DC environments. The integrated linear current controller simplifies design by eliminating ripple current concerns. Verify that the 24-V QFN package fits the PCB layout constraints and that the ±3% accuracy meets the system's luminance uniformity requirements.
Part Context
Atmel Corporation was a leader in microcontrollers and mixed-signal components before being acquired by Microchip Technology in July 2016. Products formerly branded under Atmel are now supported under the Microchip portfolio. The MSL2024 series belongs to the LED driver family, offering specialized solutions for lighting applications with integrated power management features.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Users should consult Microchip Technology's official cross-reference tools or distributor catalogs for compatible alternatives within the MSL series or equivalent LED driver families.
