AL3022MTR-G1

Overview

The AL3022MTR-G1 is a voltage mode PWM boost controller manufactured by Diodes Incorporated, designed for high-power LED driving applications. It operates at a fixed switching frequency of 140 kHz and supports output power up to 60 W. The device utilizes an external compensation network to maintain stability across varying conditions. It is housed in a compact SO-8 package to minimize board space requirements.

Feature Summary

• Integrates voltage mode control with external compensation for stable operation
• Fixed switching frequency simplifies filter design and EMI management
• Highly integrated architecture reduces the count of required external components

Applications

• LED backlighting for LCD displays ranging from 14 to 42 inches
• High-power LED driver circuits
• General purpose boost converter designs requiring constant frequency operation

Procurement Notes

Verify the specific suffix against official Diodes Incorporated documentation to confirm pinout compatibility and thermal characteristics. Ensure the component matches the intended voltage and current ratings for the target LED string configuration before integration into the final assembly.

Selection Notes

Select this component when designing systems requiring a fixed-frequency boost topology for LED strings. The external compensation feature allows customization for specific load dynamics. Consider the SO-8 package constraints regarding thermal dissipation for maximum power loads.

Part Context

This part belongs to the AL3022 series of LED lighting drivers. It serves as a specialized solution for display manufacturers seeking cost-effective backlighting drivers. The series focuses on reducing system complexity through high integration levels.

Replacement Considerations

Consult official substitution lists for direct replacements. Verify that any alternative maintains the 140 kHz frequency and SO-8 footprint to ensure mechanical and electrical compatibility without redesigning the PCB layout.
