Overview
The AL8808WT-7 is an LED lighting driver IC from Diodes Incorporated, featuring a buck topology with an integrated internal switch. It delivers regulated LED current up to 1A and supports both analog and PWM dimming controls. The device operates within a supply voltage range of 6V to 30V and functions at a switching frequency of 1MHz. It is housed in a 5-pin TSOT-25 surface-mount package. The component is designed for high-efficiency LED applications, offering adjustable output voltage and compliance with RoHS standards.
Feature Summary
- Integrates a high-voltage internal switch capable of handling up to 1A output current
- Supports precise brightness control through combined analog and PWM dimming capabilities
- Utilizes step-down (buck) converter topology for efficient power regulation
Applications
- General LED lighting systems requiring constant current drive
- Battery-powered LED fixtures operating within wide input voltage ranges
- Evaluation boards for buck and boost LED driver designs
Procurement Notes
Verify the specific suffix 'WT-7' against official Diodes Incorporated documentation to confirm tape and reel packaging quantities and pin configuration. Ensure compatibility with existing PCB footprints for the TSOT-25 package. Cross-reference the datasheet revision date to validate thermal performance specifications under intended load conditions before finalizing procurement.
Selection Notes
Select this component when a compact solution with an integrated switch is required for buck-mode LED driving. It is suitable for applications needing simultaneous analog and PWM dimming support. Consider the 6V to 30V input range for flexibility in power supply design. Verify that the 1A current limit meets the specific LED string requirements without exceeding thermal constraints of the TSOT-25 package.
Part Context
Part of the AL88 series from Diodes Incorporated, designed for versatile LED illumination tasks. The AL8808 variant specifically targets cost-sensitive applications by integrating the power switch, reducing external component count. It complements other drivers in the family by offering a balance between performance and simplicity in a small outline package.
Replacement Considerations
Consult official Diodes Incorporated substitution guides for direct equivalents. Verify pin-to-pin compatibility and electrical parameter alignment if considering alternative manufacturers. No public substitute part numbers are confirmed in the provided source material.
