Overview
The AL8860WT-7 is a monolithic Buck LED driver IC from Diodes Incorporated, designed for high-efficiency constant current regulation. It operates with an input voltage range of 4.5 V to 40 V and delivers up to 1.5 A output current. The device integrates a power switch and supports PWM dimming for brightness control. It functions at a switching frequency of 1 MHz, enabling the use of small external components. The IC is housed in a TSOT-23-5 surface-mount package and is rated for operation between -40°C and 105°C.
Feature Summary
- Integrates a high-side power switch for compact design
- Supports analog and PWM dimming methods
- Includes open LED protection circuitry
Applications
- General LED lighting fixtures
- LED backlighting systems
- Portable battery-powered LED lamps
Procurement Notes
Verify the specific output current rating (1 A vs 1.5 A) against the official datasheet, as distributor listings show conflicting specifications. Confirm the operating temperature range (-40°C to 105°C or 125°C) matches the application requirements. Ensure the TSOT-23-5 package footprint aligns with the PCB layout. Check RoHS compliance status directly from the manufacturer's documentation before procurement.
Selection Notes
Select this component for applications requiring a single-channel Buck topology with integrated switching. It is suitable for designs needing wide input voltage compatibility and high efficiency. Consider the thermal performance within the TSOT-23-5 package when determining heat dissipation strategies. Verify that the required dimming interface is compatible with the internal control logic.
Part Context
This part belongs to the AL88 series of LED drivers from Diodes Incorporated. It is functionally similar to the AL8808 and AL8861 models but differs in maximum output current and specific feature sets. The AL8860 variant is specifically engineered for higher current applications compared to the 1 A variants in the same family.
Replacement Considerations
The AL8861WT-7 is a related part number within the same product family. Verify if the lower current rating (1 A) of the AL8861 meets the design needs. Cross-reference pinouts and electrical characteristics with the official datasheets to ensure compatibility.
