Overview
The MP4033GK-Z is a TRIAC dimmable, primary side control offline LED controller with active PFC. It operates from an 11V to 27V supply voltage and features a flyback topology without internal switches. The device supports analog, PWM, and TRIAC dimming methods. It is housed in a 10-MSOP package and functions within a junction temperature range of -40°C to 125°C. This IC provides precise LED current regulation using proprietary primary-side sensing techniques.
Feature Summary
- Primary side control eliminates the need for secondary feedback circuits and optocouplers
- Adaptive dimmer type detection ensures compatibility with various TRIAC dimmers
- Integrated active PFC improves power factor in single-stage converter applications
- Programmable current foldback extends LED lifespan under thermal stress
Applications
- Commercial isolated LED lighting systems
- Industrial lighting fixtures requiring TRIAC dimming
- Applications needing PWM input for analog dimming control
- Warm daylight tuning applications with color temperature control
Procurement Notes
Verify the suffix 'Z' indicates RoHS compliance when ordering. Confirm the 'GK' designation corresponds to the 10-MSOP package variant. Ensure design requirements align with the specified 11V to 27V operating voltage range. Check datasheet for specific pinout configurations relative to the MSOP-10 footprint. Validate thermal management strategies for the 125°C maximum junction temperature limit.
Selection Notes
Select this component for designs prioritizing high power factor correction and wide TRIAC dimmer compatibility. It is suitable for isolated topologies where primary side regulation simplifies the bill of materials. Consider the integrated protection features for enhanced system reliability. Evaluate the critical conduction mode operation for reduced switching losses compared to hard-switched alternatives.
Part Context
The MP4033 series represents Monolithic Power Systems' solution for AC-DC isolated LED drivers. The MP4033GK-Z specifically denotes the RoHS-compliant version in the MSOP-10 package. It succeeds earlier generations like the MP4030, offering improved dimming performance and active PFC integration. The part is designed for commercial and industrial lighting sectors.
Replacement Considerations
MP4030GS-P serves as a functional predecessor but lacks active PFC. MP4033GSE-Z offers an alternative SOIC-14 package option. Verify pin-to-pin compatibility if substituting within the same family. Review updated protection thresholds when moving between different package variants.
