Overview
The MP4056GK-P is a non-isolated offline LED controller from Monolithic Power Systems designed for TRIAC dimmable lighting applications. It integrates active power factor correction (PFC) and utilizes a buck-boost topology to regulate output current. The device supports an input voltage range of 85 VAC to 305 VAC, accommodating universal AC line inputs. It is housed in a standard surface-mount package suitable for automated assembly processes.
Feature Summary
- Integrates active PFC functionality for improved power efficiency
- Supports TRIAC dimming compatibility for residential lighting control
- Employs a buck-boost topology for flexible LED string configurations
Applications
- TRIAC dimmable LED downlights
- Non-isolated LED bulb drivers
- General solid-state lighting fixtures
Procurement Notes
Verify the specific suffix 'GK-P' against official MPS documentation to confirm package type and tape/reel specifications. Ensure that the selected variant matches the required thermal performance and regulatory compliance standards for the target market. Cross-reference the datasheet revision date with manufacturing records to guarantee component authenticity and consistency.
Selection Notes
Select this component for designs requiring integrated PFC and TRIAC dimming without isolation transformers. Evaluate the buck-boost topology suitability for the intended LED forward voltage range relative to the minimum and maximum AC input voltages. Confirm that the MSOP-10 package provides adequate thermal dissipation for the expected power levels in the application environment.
Part Context
This part belongs to the MP4056 series of LED lighting driver ICs. It shares functional similarities with other non-isolated controllers but is distinguished by its specific integration of active PFC and TRIAC dimming capabilities. The series targets cost-sensitive, high-performance lighting solutions where isolation is not required.
Replacement Considerations
Consult official MPS substitution guides for verified alternatives. Generic cross-references are not supported due to unique internal control architectures.
