Overview
The MP4054AGJ-P is a primary-side control offline LED driver IC from the MP4054A series, manufactured by Monolithic Power Systems. It utilizes a flyback topology and operates within an input voltage range of 12 V to 28 V. The device provides a regulated output voltage of 6.7 V and supports PWM dimming for brightness control. Designed for surface-mount installation in a TSOT-23-8 package, it functions reliably across a temperature range of -40 °C to +125 °C with a maximum power dissipation of 1.25 W.
Feature Summary
- Integrates primary-side regulation for simplified circuit design without requiring secondary-side feedback components.
- Supports pulse-width modulation (PWM) dimming to enable precise brightness control capabilities.
- Operates efficiently within a wide input voltage window suitable for various low-voltage AC/DC applications.
Applications
- Offline LED lighting systems
- General illumination drivers
- Low-power LED modules
Procurement Notes
Verify the specific suffix P against official Monolithic Power Systems documentation to confirm packaging details and compliance status. Ensure the TSOT-23-8 footprint matches your PCB layout requirements. Cross-reference the MP4054A series datasheet for thermal management guidelines given the 1.25 W power dissipation limit. Confirm RoHS compliance through the manufacturer's official product compliance database before finalizing procurement specifications.
Selection Notes
Select this component when designing compact offline LED drivers requiring primary-side control to reduce bill of materials cost. The TSOT-23-8 package suits space-constrained designs. Verify that the required output voltage aligns with the 6.7 V specification or adjust transformer turns ratio accordingly. Ensure the application environment stays within the -40 °C to +125 °C operating temperature range for reliable performance.
