MP4056GK-Z

Overview

The MP4056GK-Z 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 SMD/SMT installation. Available in SOIC-8 packaging, it integrates critical protection features including output overvoltage, short circuit, and thermal protection for reliable operation in lighting applications.

Feature Summary

Integrates active power factor correction (PFC) with TRIAC dimming compatibility
Supports adaptive dimmer type detection and phase-cut dimming control
Includes comprehensive protection mechanisms such as OVP, OCP, and OTP

Applications

Non-isolated LED lighting systems
TRIAC dimmable general illumination fixtures
Offline AC-DC LED driver designs requiring high power factor

Procurement Notes

Verify the package suffix 'K' corresponds to the SOIC-8 configuration before ordering. Confirm RoHS compliance status through official manufacturer documentation. Ensure design inputs match the specified 85 VAC to 305 VAC operating range. Cross-reference the specific revision level against current datasheets to guarantee functional equivalence.

Selection Notes

Select this component for non-isolated topologies where size reduction is prioritized over galvanic isolation. It is suitable for applications requiring integrated PFC and dimming capabilities without external controllers. Evaluate thermal management requirements given the SOIC-8 package constraints. Verify compatibility with local TRIAC dimmers for optimal performance.

Part Context

This part belongs to the MP4056 family of non-isolated LED controllers designed for high-efficiency lighting solutions. The series emphasizes simplified bill of materials by integrating PFC and constant current regulation. It targets cost-sensitive commercial and residential lighting markets requiring robust dimming performance.
