AL8862FF-7

Overview

The AL8862FF-7 is a step-down DC/DC converter designed to drive LEDs with constant current. It operates with an input supply voltage from 5V to 60V and provides a regulated output of 1A. The device supports analog and PWM dimming for brightness control. It features an internal switch and is housed in a compact 6-DFN (3x3) package. The operating temperature range extends from -40°C to 105°C, ensuring reliability in various environments.

Feature Summary

• Integrated step-down topology with internal power switch
• Supports both analog and PWM dimming methods
• Wide input voltage range up to 60V
• Constant current regulation for LED applications

Applications

• Commercial lighting systems
• Industrial lighting fixtures
• General LED illumination modules

Procurement Notes

Verify the specific suffix FF-7 corresponds to the 6-DFN (3x3) package and tape-and-reel quantity when ordering. Confirm that the component status remains active as specifications may change. Ensure compatibility with existing PCB footprints for the U-DFN3030-6 form factor before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring a wide input voltage range up to 60V and precise 1A constant current regulation. The integrated internal switch simplifies design by reducing external component count. Consider the 6-DFN package size for space-constrained layouts. Verify thermal management requirements given the 105°C junction temperature capability.

Part Context

This part belongs to the AL8862 family of LED drivers manufactured by Diodes Incorporated. The family includes variants such as AL8862SP-13 in an 8SO package. The AL8862FF-7 specifically utilizes a smaller 6-DFN footprint, offering a compact solution for modern electronic designs compared to larger package options within the same functional series.

Replacement Considerations

Check for direct substitutes like the AL8862QFGEAW-7 if different packaging or quality grades are required. Ensure any replacement maintains the 60V input limit and 1A output current specification. Verify pinout compatibility for the 6-DFN package to avoid redesigning the PCB layout during substitution.
