Overview
The MP4033GSE-Z is a TRIAC-dimmable, primary side-control offline LED lighting controller with active PFC. It utilizes a single-stage converter for isolated applications and employs proprietary real-current control via primary-side information. The device operates in boundary conduction mode to reduce MOSFET switching losses. It features adaptive dimmer type detection, programmable current fold-back for LED lifetime extension, and color temperature control. Protection mechanisms include output over-voltage, short-circuit, winding short circuit, ZCD pin short circuit, UVLO, and over-temperature protection with auto-restart.
Feature Summary
- Primary-side control eliminating the need for secondary-side feedback circuits
- Adaptive dimmer type detection with phase-cut-based dimming control
- Programmable current fold-back to prolong LED lifetime
- Integrated active PFC operating in boundary conduction mode
Applications
- Solid-state lighting up to 50W
- Industrial and commercial lighting
- Residential lighting
Procurement Notes
Verify the specific suffix 'GSE' against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure compatibility with existing BOM requirements for isolation topology and dimming interface standards before finalizing procurement orders.
Selection Notes
Select this component for designs requiring high power factor correction without optocouplers. It is suitable for applications needing deep dimming ranges and warm sunset dimming capabilities. Consider the MSOP-10 or SOIC-14 package availability when designing PCB footprints.
Part Context
This part belongs to the MP4033 series of AC-DC LED drivers. It serves as an enhanced version of earlier models like the MP4030, offering improved dimmer compatibility and additional protection features. The series supports both TRIAC dimming and PWM input analog dimming functions.
