AL8807W5-7

Overview

The AL8807W5-7 is a high-efficiency, low EMI buck LED driver from Diodes Incorporated, designed for constant current LED applications. It operates with an input voltage range of 6 V to 36 V and supports up to 1 A output current. The device integrates a low-side N-channel switch and features analog and PWM dimming capabilities. Operating at a typical switching frequency of 1 MHz, it drives multiple LEDs in series within a compact SOT-25 package. It functions across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates a low-side N-channel power switch for simplified external component count
• Supports both analog and pulse-width modulation (PWM) dimming methods
• Designed for high efficiency and low electromagnetic interference (EMI)
• Capable of driving multiple LEDs in series from a wide input voltage range

Applications

• General lighting systems requiring constant current regulation
• Automotive interior and exterior lighting modules
• Portable electronic devices with LED indicators or displays
• Battery-powered lighting applications

Procurement Notes

Verify the specific suffix W5-7 corresponds to the required tape and reel packaging configuration. Confirm RoHS compliance status through the latest manufacturer documentation. Check for any product change notifications regarding leadframe materials or fabrication sources. Ensure the ordering part number matches the exact pinout and functional specifications required for the design.

Selection Notes

Select this component when a compact solution for driving multiple series-connected LEDs is needed. It is suitable for designs requiring a wide input voltage range up to 36 V. Consider its 1 MHz switching frequency for smaller passive components. Verify that the thermal performance in the SOT-25 package meets the application's heat dissipation requirements under maximum load conditions.

Part Context

This part belongs to the AL88 series of LED drivers from Diodes Incorporated. It is specifically engineered as a step-down (buck) converter topology optimized for LED illumination. The W5-7 suffix indicates the specific packaging variant within this family. It serves as a dedicated driver IC rather than a general-purpose regulator.

Replacement Considerations

Check for direct substitutes within the AL88 series that may offer different packaging options. Verify compatibility with existing PCB footprints if considering alternative manufacturers. Ensure that any replacement maintains the same 36 V maximum input rating and 1 A current capability.
