Overview
The MP4088GN-P is a non-isolated, high power factor correction (PFC) TRIAC dimmable LED driver IC designed for AC mains applications. It integrates a Buck-Boost and Flyback topology to drive LEDs up to 10W directly from 230VAC input. The device operates within an input voltage range of 198VAC to 265VAC at 50Hz/60Hz. Key electrical parameters include a maximum power dissipation of 2.6 W and a maximum supply current of 6.1 mA. It features brightness control and dimming capabilities compatible with TRIAC dimmers. The component is housed in an SOIC-EP-8 surface-mount package.
Feature Summary
- Integrates active PFC functionality for high efficiency in non-isolated LED lighting applications
- Supports TRIAC dimming for compatibility with standard residential phase-cut dimmers
- Combines Buck-Boost and Flyback topologies for flexible LED string configuration
Applications
- Non-isolated LED downlights
- TRIAC dimmable LED bulbs
- Low-power general illumination fixtures
Procurement Notes
Verify the specific suffix 'GN' corresponds to the SOIC-EP-8 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design specifications align with the 2.6 W power dissipation limit and 6.1 mA supply current constraints for thermal management.
Selection Notes
Select this component for designs requiring integrated PFC and TRIAC dimming in a non-isolated topology. The SOIC-EP-8 package offers improved thermal performance compared to smaller packages like TSOT-23. Verify that the application voltage range matches the 198VAC to 265VAC specification. Consider the 10W output capability when sizing the LED load.
Part Context
The MP4088 belongs to the MP4088 series of single-stage offline LED controllers by Monolithic Power Systems. This series targets cost-sensitive, compact lighting solutions where isolation is not required. The GN suffix typically denotes the SOIC-EP-8 package option within this family, distinguishing it from other pinout or thermal variants.
Replacement Considerations
Consult official MPS documentation for qualified replacements. Cross-reference with similar non-isolated TRIAC dimmable drivers if package or pinout compatibility is critical.
