MP4054AGJ-Z

Overview

The MP4054AGJ-Z is a primary-side control offline LED driver IC from the MP4054 series, manufactured by Monolithic Power Systems. It utilizes a flyback topology with a single output and operates within a supply voltage range of 12 V to 28 V, delivering an output voltage of 6.7 V. The device supports PWM dimming for brightness control and functions at a switching frequency of 5 kHz. Designed for surface-mount installation in TSOT-23-8 packages, it ensures reliable performance across a wide operating temperature range from -40 °C to +125 °C.

Feature Summary

• Primary-side regulation architecture eliminates the need for optocouplers and secondary-side feedback components.
• Integrated PWM dimming capability enables precise brightness control for LED lighting applications.
• Compact TSOT-23-8 package design facilitates space-constrained PCB layouts.

Applications

• Offline AC/DC LED lighting drivers
• General illumination systems requiring primary-side control
• Compact LED lamp designs

Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and electrical characteristics, as variations may exist within the MP4054 family. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly planning. Ensure the selected package variant matches the intended footprint and thermal management strategy for the target application environment.

Selection Notes

Select this component for applications requiring isolated flyback conversion with simplified control loops. The primary-side regulation approach reduces bill-of-materials cost by removing secondary sensing elements. Evaluate the 5 kHz switching frequency against electromagnetic interference constraints. Verify that the 6.7 V output voltage aligns with the forward voltage requirements of the target LED string configuration.
