Overview
The MP4057AGK-Z is a single-stage, single-chip LED lighting driver IC designed for smart LED applications. It integrates Buck-Boost and Flyback topologies within an MSOP-10 package. The device operates with an input voltage range of 4 V to 27 V and supports PWM dimming. Key electrical parameters include a maximum output current of 1 mA, a power dissipation of 830 mW, and a maximum supply current of 500 uA. It functions at a working frequency of 60 kHz and withstands temperatures from -40 C to +125 C.
Feature Summary
- Single-stage single-chip solution for smart LED applications
- Integrates Buck-Boost and Flyback topologies
- Supports PWM dimming functionality
Applications
- Smart LED lighting systems
- LED lighting driver circuits
- General illumination applications requiring single-stage conversion
Procurement Notes
Verify the specific suffix Z against official Monolithic Power Systems documentation to confirm packaging and reel specifications. Ensure compatibility with MSOP-10 surface mount requirements. Cross-reference the datasheet for RoHS compliance details and thermal management needs given the 830 mW power dissipation limit. Confirm availability through authorized channels as distribution status may vary.
Selection Notes
Select this component for designs requiring a compact, single-stage LED driver with integrated Buck-Boost and Flyback capabilities. Consider the 4 V to 27 V input range and 60 kHz operating frequency for appropriate circuit matching. Evaluate the MSOP-10 package size constraints and thermal performance relative to the 830 mW dissipation rating. Verify that PWM dimming meets system control requirements.
Part Context
The MP4057AGK-Z belongs to the MP4057 series of LED lighting drivers from Monolithic Power Systems. It is part of a family offering single-stage solutions for smart lighting. Related variants include the MP4057AGK-P, which shares similar electrical characteristics but may differ in packaging or ordering suffixes. The series targets efficient integration for modern LED applications.
Replacement Considerations
The MP4057AGK-P is a documented variant within the same product line. Verify if the suffix difference impacts packaging or specific ordering attributes before substitution.
