AL8891T16E-13

Overview

The AL8891T16E-13 is a synchronous buck LED driver IC from Diodes Incorporated, designed for high-efficiency constant current regulation. It features an integrated high-side MOSFET with 200mΩ resistance and a low-side MOSFET with 130mΩ resistance. The device supports an input voltage range of 4.5V to 65V and delivers a maximum output current of 2A. Operating at a fixed frequency of 2.5MHz, it provides an output voltage range of 1V to 65V. The component operates within a temperature range of -40°C to +105°C and includes overtemperature thermal protection with auto-restart functionality.

Feature Summary

• Integrates high-side and low-side MOSFETs for efficient synchronous buck conversion
• Supports analog and PWM dimming methods for precise light control
• Includes overtemperature thermal protection with automatic restart capability

Applications

• LED lighting systems requiring constant current regulation
• General illumination applications utilizing buck topology
• Designs supporting both analog and PWM dimming interfaces

Procurement Notes

Verify the specific suffix 'T16E' corresponds to the TSSOP-16EP package and tape-and-reel quantity when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure the selected variant matches the required marking code for production assembly traceability.

Selection Notes

Select this component for applications requiring a wide input voltage range up to 65V and high output current capabilities. The integrated power switches reduce external component count compared to asynchronous designs. Consider the 2.5MHz switching frequency for balancing efficiency against electromagnetic interference requirements in compact form factors.

Part Context

This part belongs to the AL8891 series of non-isolated LED drivers manufactured by Diodes Incorporated. The series focuses on single-channel solutions for general lighting. The T16E suffix indicates the specific package configuration and packaging method, distinguishing it from other variants in the same functional family.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify pin compatibility and electrical specifications before replacing existing inventory.
