Overview
The MP4050AGJ-P is a non-isolated, high-brightness LED driver IC from Monolithic Power Systems. It utilizes a buck topology to drive LEDs with a single output channel. The device operates within an input voltage range of 4.1 V to 5 V and features a fixed switching frequency of 22 kHz. Packaged in a TSOT-23-5 form factor for surface mount installation, it is designed specifically for high brightness LED applications.
Feature Summary
- Non-isolated buck topology for efficient LED driving
- Optimized for high brightness LED applications
- Fixed low-frequency operation at 22 kHz
Applications
- High brightness LED lighting systems
- General illumination circuits
- Compact LED driver designs
Procurement Notes
Verify the specific package variant against design requirements, as the MP4050 series includes alternative packages such as SOIC-8. Confirm that the 22 kHz operating frequency aligns with electromagnetic interference constraints. Ensure the input voltage range of 4.1 V to 5 V matches the system power supply specifications before integration.
Selection Notes
Select this component when a non-isolated solution is acceptable and space is limited due to the TSOT-23-5 package. The fixed 22 kHz frequency may require larger external components compared to higher frequency alternatives. Consider the MP4050AGS-P if an SOIC-8 package is preferred for thermal or manufacturing reasons.
Part Context
This part belongs to the MP4050 series of LED drivers from Monolithic Power Systems. The series offers various package options including SOIC-8 variants like the MP4050AGS-P. These devices are engineered for compact, cost-effective LED lighting solutions requiring simple control architectures.
Replacement Considerations
The MP4050AGS-P serves as a package-compatible alternative within the same series, offering identical electrical characteristics in an SOIC-8 footprint.
