Overview
The MP4033GK-P is an AC-DC LED driver IC from Monolithic Power Systems, designed for isolated offline lighting applications. It features primary-side control with active PFC and supports TRIAC, PWM, and analog dimming. The device operates within a supply voltage range of 11V to 27V and utilizes a flyback topology. Packaged in a 10-MSOP (10-TFSOP) surface-mount case, it functions across a junction temperature range of -40°C to 125°C.
Feature Summary
- Primary-side regulation eliminates the need for secondary feedback circuits and optocouplers.
- Adaptive dimmer type detection ensures compatibility with TRIAC dimmers and wide dimming ranges.
- Integrated active PFC and critical conduction mode operation reduce switching losses.
- Comprehensive protection mechanisms include output overvoltage, short circuit, and thermal shutdown.
Applications
- Commercial and industrial isolated LED lighting systems
- TRIAC dimmable general illumination fixtures
- Applications requiring high power factor correction
Procurement Notes
Verify the specific suffix 'P' against official MPS documentation to confirm package type and tape/reel specifications. Ensure the component meets RoHS3 compliance requirements for your region. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current production status and availability before finalizing procurement plans.
Selection Notes
Select this component for designs requiring simplified isolation via primary-side control. It is suitable for applications needing precise LED current regulation without secondary sensing. Consider its support for multiple dimming methods if user-adjustable brightness is required. Verify that the 10-MSOP footprint fits the target PCB layout constraints.
Part Context
This part belongs to the MP4033 family of enhanced TRIAC-dimmable, primary-side control offline LED controllers. It serves as a successor or alternative to older models like the MP4030, offering improved dimming compatibility and integrated active PFC. The family targets cost-sensitive, high-performance isolated LED drivers.
Replacement Considerations
MP4033GK-Z is a verified substitute within the same series, differing primarily in packaging or environmental compliance suffixes. MP4030GS-P is listed as an alternative for new designs but lacks some enhanced features. Verify pinout and electrical parameters before substitution.
