Overview
The MP4033GS is a TRIAC dimmable, primary side control offline LED controller with active PFC. It operates within an input voltage range of 11 V to 27 V and supports a maximum power dissipation of 1.3 W. The device functions across a temperature range of -40°C to +125°C TJ. It utilizes a SOIC-8 package for surface mount installation.
Feature Summary
- Primary side regulation eliminates the need for secondary feedback circuits
- Integrated active PFC functionality for high power factor correction
- Adaptive dimmer type detection ensures compatibility with TRIAC dimmers
- Supports PWM input for analog dimming applications
Applications
- Isolated commercial lighting systems
- Industrial lighting fixtures
- TRIAC dimmable LED drivers
- Warm daylight tuning applications
Procurement Notes
Verify the specific suffix (e.g., GS, GSE) against official datasheets to confirm package type and thermal characteristics. Confirm current availability status as distribution channels may report limited stock or end-of-life notices. Ensure component authenticity through authorized suppliers to guarantee performance reliability in safety-critical lighting designs.
Selection Notes
Select this component for isolated flyback topologies requiring integrated PFC and TRIAC dimming capabilities. Evaluate thermal management requirements given the 1.3 W power dissipation limit in the SOIC-8 package. Consider system complexity reduction due to primary side control features which remove the need for optocouplers or secondary sensing resistors.
Part Context
This part belongs to the MP4033 family of AC-DC LED controllers designed for high-performance lighting applications. It replaces older generations like the MP4030 series by offering enhanced dimming compatibility and integrated power factor correction without external auxiliary windings.
Replacement Considerations
Officially recommended replacements include MP4033GK-Z and MP4033GSE-P. Verify pinout compatibility and thermal performance when transitioning between MSOP-10 and SOIC-8 packages.
