MP4027GJ-Z

Overview

The MP4027GJ-Z is an offline primary-side regulation (PSR) LED controller from Monolithic Power Systems, designed for flyback topologies. It operates within a supply voltage range of 12 V to 28 V and functions at a switching frequency of 70 kHz. The device supports PWM dimming for brightness control and is housed in an SOIC-8 package. It features a power dissipation rating of 1.25 W and operates across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates primary-side regulation for simplified design without optocouplers
• Supports pulse-width modulation (PWM) dimming for precise brightness adjustment
• Includes built-in protection mechanisms for reliable operation

Applications

• Offline LED lighting drivers
• General illumination systems
• AC/DC LED converters

Procurement Notes

Verify the specific suffix against official documentation to confirm pinout and electrical characteristics. Ensure the component matches the required flyback topology and input voltage specifications. Confirm RoHS compliance status through the manufacturer's environmental declaration before integration into production designs.

Selection Notes

Select this component for applications requiring a single-output flyback converter with integrated dimming capabilities. The SOIC-8 package suits surface-mount assembly processes. Verify that the 70 kHz operating frequency aligns with electromagnetic interference requirements and thermal management constraints for the target enclosure.

Part Context
