• Supports Buck-Boost and Flyback topologies
• PWM dimming control interface

Applications

• Smart LED lighting systems

Procurement Notes

Verify the specific suffix 'P' against the manufacturer's official documentation to confirm packaging details. Ensure compatibility with the MSOP-10 package footprint during PCB layout. Confirm that the component meets required environmental standards for the intended deployment environment before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring a compact, single-stage LED driver solution. The fixed 60 kHz switching frequency simplifies magnetic component selection. Verify that the 4 V to 27 V input range aligns with the system power supply specifications and that the MSOP-10 package fits the available board space constraints.

Part Context

This part belongs to the MP4057 series of LED drivers designed for smart lighting applications. It integrates control logic and power stages into a single chip to reduce external component count. The series targets cost-sensitive and space-constrained LED illumination products requiring reliable constant current regulation.

Replacement Considerations

Check for MP4057AGK-Z as a potential alternative variant within the same family. Verify pinout compatibility and electrical parameter equivalence before substitution.
