Overview
The MP4050AGS-Z is a non-isolated, high brightness LED driver IC manufactured by Monolithic Power Systems. It utilizes a buck topology and operates as an AC/DC offline switcher with a single output channel. The device features an integrated internal MOSFET and supports PWM dimming capabilities. It is housed in an 8-SOIC package (3.90mm width) and is designed for surface mount installation. The component functions within an input voltage range of 85 VAC to 265 VAC and maintains an operating junction temperature range from -40°C to +125°C.
Feature Summary
- Integrates a high-voltage power MOSFET within the IC package to reduce external component count.
- Supports PWM dimming control for adjustable LED brightness regulation.
- Designed for non-isolated applications requiring constant current output.
Applications
- General lighting systems
- Commercial illumination fixtures
Procurement Notes
Verify the specific suffix 'Z' indicates RoHS compliance status during procurement. Confirm the 8-SOIC package dimensions match the target PCB footprint. Ensure the design accommodates the required thermal dissipation for the specified power rating. Validate that the AC input voltage range aligns with the local mains supply standards.
Selection Notes
Select this component for designs requiring a compact, non-isolated solution for high-brightness LEDs. The integrated MOSFET simplifies the bill of materials compared to discrete solutions. Consider the 8-SOIC package constraints for thermal management and board space. Verify compatibility with the intended dimming interface requirements before finalizing the design.
Part Context
This part belongs to the MP4050 series of LED drivers from Monolithic Power Systems. The series focuses on non-isolated, high-brightness LED applications. The AGS variant specifically denotes the 8-SOIC package configuration. This series is distinct from other MPS LED drivers like the MP4033 or MP4013 which offer different topologies or pin counts.
Replacement Considerations
The MP4050AGS-P is listed as a direct substitute for the MP4050AGS-Z.
FAQ
