Overview
The MP4068GS-Z is a non-isolated TRIAC dimmable PFC LED driver IC from Monolithic Power Systems. It integrates power factor correction and constant current regulation using Buck or Buck-Boost topologies. The device operates with an input voltage range of 4.1 V to 5 V and features a fixed switching frequency of 22 kHz. Designed for brightness control, it supports Triac dimming functionality. The component is housed in an SOIC-8-7A package and is suitable for surface mount installation.
Feature Summary
- Integrates active power factor correction with constant current regulation
- Supports TRIAC dimming for compatibility with standard wall switches
- Utilizes Buck or Buck-Boost topology for flexible LED string configurations
Applications
- TRIAC dimmable LED lighting fixtures
- Non-isolated LED driver circuits
- Brightness controlled LED applications
Procurement Notes
Verify the specific suffix Z against official datasheets to confirm RoHS compliance status. Confirm that the SOIC-8-7A package dimensions match your PCB footprint requirements. Ensure the 4.1 V to 5 V supply range aligns with your system design. Check humidity sensitivity levels for proper storage and reflow soldering profiles.
Selection Notes
Select this component when a non-isolated solution with integrated PFC is required. It is appropriate for designs needing TRIAC dimming compatibility without external controllers. Consider the 22 kHz operating frequency for EMI management. Verify that the Buck/Buck-Boost topology suits the LED forward voltage relative to the supply rail.
Part Context
This part belongs to the MP4068 series of LED drivers. It is distinct from other MPS models like the MP4088GS-Z which may offer different pinouts or feature sets. The GS-Z designation indicates the specific package type and environmental compliance. It serves as a specialized controller for efficient AC/DC conversion in lighting systems.
Replacement Considerations
Consult official substitution lists for verified alternatives. Cross-reference pinouts and electrical characteristics carefully. Generic replacements may lack specific TRIAC dimming performance.
