Overview
The MP4033GK-Z is an AC-DC LED driver IC from Monolithic Power Systems, designed for isolated flyback topologies. It operates within a supply voltage range of 11V to 27V and features primary-side control to eliminate the need for secondary feedback circuits. The device supports TRIAC, PWM, and analog dimming methods. It integrates active power factor correction (PFC) and operates in critical conduction mode to reduce switching losses. The component is housed in a 10-MSOP package and functions across a junction temperature range of -40°C to 125°C.
Feature Summary
- Primary-side regulation eliminates the requirement for secondary feedback circuits or optocouplers.
- Adaptive dimmer type detection enables compatibility with TRIAC dimmers and wide dimming ranges.
- Integrated active PFC ensures high power factor performance in single-stage converters.
- Comprehensive protection mechanisms include output overvoltage, short circuit, and thermal shutdown.
Applications
- Commercial and industrial lighting systems
- Isolated offline LED illumination fixtures
- Applications requiring warm dimming capabilities
Procurement Notes
Verify the specific suffix 'GK' corresponds to the 10-MSOP package variant when sourcing. Confirm RoHS3 compliance status as required by regional regulations. Ensure the ordering quantity aligns with manufacturer standard packaging specifications. Cross-reference the full part number against official distributor catalogs to avoid substitution errors during procurement.
Selection Notes
Select this component for designs requiring isolated flyback conversion with integrated PFC. It is suitable for applications needing precise current regulation without secondary sensing. Consider the 10-MSOP package constraints for thermal management. Verify input voltage requirements fall within the specified 11V to 27V operational window for optimal performance.
Part Context
This part belongs to the MP4033 family of enhanced TRIAC-dimmable, primary-side control offline LED controllers. The series includes variants such as MP4030 and MP4033GS-Z. The MP4033GK-Z specifically denotes the version packaged in a 10-lead MSOP format, distinguishing it from SOIC-8 or SOIC-14 alternatives within the same functional family.
Replacement Considerations
MP4030 is listed as an alternative for existing customers, though MP4033 is recommended for new designs. Other family members like MP4033GS-Z share similar functionality but differ in package configuration. Verify pinout compatibility before substituting any variant.
