Overview
The MP4056GSE-P is a non-isolated, TRIAC dimmable offline LED controller with active PFC from Monolithic Power Systems. It utilizes a Buck-Boost topology to drive LEDs directly from AC mains. The device operates within an input voltage range of 85 VAC to 305 VAC and supports power factor correction in critical conduction mode. It features adaptive dimmer type detection, PWM/Analog dimming, and warm dimming capabilities. Protection mechanisms include OVP, OCP, OTP, and ZCD pin short protection.
Feature Summary
- Adaptive TRIAC dimmer type detection for wide compatibility
- Integrated active PFC with critical conduction mode operation
- Supports PWM and analog dimming with warm dimming functionality
- Comprehensive protection suite including OVP, OCP, and OTP
Applications
- Non-isolated TRIAC dimmable LED lighting fixtures
- Offline LED drivers requiring active PFC
- Warm dimming applications with color temperature control
- General purpose LED illumination systems
Procurement Notes
Verify the specific suffix 'GSE' corresponds to the required package variant (SOIC-8) and lead-free status as per the manufacturer's current datasheet. Confirm that the ordering information matches the exact part number for the intended PCB footprint. Ensure compliance with humidity sensitivity handling requirements during assembly.
Selection Notes
Select this component for non-isolated designs requiring integrated PFC and TRIAC dimming. It is suitable for applications needing precise line and load regulation without isolation barriers. Consider the Buck-Boost topology for wide input voltage ranges. Evaluate thermal management needs due to the integrated nature of the controller.
Part Context
The MP4056 series includes variants such as MP4056GK, MP4056GS, and MP4056GSE, differing primarily in package types like MSOP-10, SOIC-14, and SOIC-8. The GSE suffix specifically denotes the SOIC-8 package option within the MP4056 family of non-isolated LED controllers.
Replacement Considerations
Direct substitutes are not explicitly listed in the provided documentation. Designers should evaluate other MPS non-isolated LED controllers with similar Buck-Boost topologies and TRIAC dimming support if pin-to-pin compatibility is not strictly required.
