Overview
The AL8890QT16E-13 is a synchronous buck LED driver from Diodes Incorporated, designed for high-efficiency constant current regulation. It operates with an input voltage range of 3.8V to 60V and supports output voltages from 0.8V up to nearly 100% of VIN. The device delivers up to 3.5A output current and features a fixed switching frequency of 2.5MHz. It includes integrated power MOSFETs and offers 1% VFB accuracy. The component is housed in a TSSOP-16EP package and is AEC-Q100 Grade 1 qualified for automotive applications.
Feature Summary
- Integrated synchronous buck topology with internal power switches
- AEC-Q100 Grade 1 qualification for automotive reliability
- Wide input voltage range supporting various supply configurations
- High precision voltage feedback loop for accurate current control
Applications
- Automotive exterior lighting systems
- Interior LED illumination modules
- General-purpose DC/DC step-down conversion
- High-brightness LED drivers requiring compact form factors
Procurement Notes
Verify the specific suffix 'QT16E-13' to confirm the TSSOP-16EP package and tape-and-reel quantity. Confirm AEC-Q100 Grade 1 compliance if automotive qualification is required. Check RoHS status against regional regulations. Ensure the design accounts for thermal dissipation in the exposed pad package. Validate input/output voltage ranges against the target application circuit requirements before ordering.
Selection Notes
Select this component when a compact, high-efficiency synchronous buck solution is needed for LED driving or general DC/DC conversion. The 2.5MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. The wide input voltage range provides flexibility for battery-powered or varying supply environments. Consider the TSSOP-16EP package for its thermal performance and pin count balance.
Part Context
This part belongs to the AL8890Q family of LED drivers from Diodes Incorporated. It shares core functionality with variants like AL8890FVBW-13 but differs in packaging and reel specifications. The AL8890 series is positioned as a versatile solution for both automotive and industrial LED applications, emphasizing efficiency and integration.
Replacement Considerations
Direct substitutes include other AL8890Q variants such as AL8890FVBW-13, noting differences in package type (U-QFN vs TSSOP) and reel quantity. Verify pin compatibility and thermal characteristics when cross-referencing with similar synchronous buck LED drivers from other manufacturers.
