Overview
The AL88902FVBW-13 is a synchronous buck converter from Diodes Incorporated, housed in a U-QFN4040-16 package. It operates with an input voltage range of 3.8 V to 60 V and delivers up to 2.5 A output current. The device features a fixed switching frequency of 2.5 MHz and offers adjustable output voltages between 5 V and 15 V. Key electrical specifications include a quiescent current of 43 uA and operation within a temperature range of -40°C to +125°C.
Feature Summary
- Integrated internal switch for compact design
- Wide input voltage capability for automotive applications
- High accuracy voltage regulation
Applications
- Automotive LED lighting systems
- General DC-DC conversion in high-voltage environments
- Industrial power management modules
Procurement Notes
Verify the specific suffix 'F' against the datasheet to confirm it denotes the standard commercial or industrial grade variant, distinct from the 'Q' automotive qualified version. Ensure the U-QFN4040-16 footprint matches the PCB layout requirements. Confirm RoHS compliance status through the official manufacturer documentation before finalizing procurement.
Selection Notes
Select this component when a wide input voltage range up to 60 V is required alongside a compact form factor. The 2.5 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Ensure the thermal design supports the U-QFN4040-16 package dissipation characteristics for the intended load current.
Part Context
This part belongs to the AL8890 series of LED drivers and switching regulators designed by Diodes Incorporated. It is specifically engineered for medium-voltage applications, offering a balance of efficiency and size. The series includes variants such as the AL88902QFVBW-13, which shares similar electrical characteristics but may differ in qualification standards.
Replacement Considerations
The AL88902QFVBW-13 is a related variant within the same family. Verify if the 'Q' suffix indicating AEC-Q100 Grade 1 qualification is necessary for the application. Other parts in the AL8890 series should be checked for pin compatibility and electrical parameter alignment.
