LT8391EUFD#TRPBF

LED Driver IC Overview

The LT8391EUFD#TRPBF is a synchronous four-switch buck-boost LED controller from Analog Devices. It regulates LED current when input voltage is above, below, or equal to output voltage. The device supports an input voltage range of 4V to 60V and features a switching frequency between 150kHz and 650kHz. It operates with a supply voltage minimum of 4V and maximum of 60V, delivering up to 60V output. Packaged in a 28-WFQFN exposed pad, it includes spread spectrum capabilities for EMI reduction.

LED Driver IC Feature Summary

Synchronous four-switch buck-boost topology enables regulation across varying input and output voltage conditions
Integrated spread spectrum technology reduces electromagnetic interference emissions
Supports analog and PWM dimming methods for precise light control

LED Driver IC Applications

LED lighting systems
Display backlights
Indicator lights

LED Driver IC Procurement Notes

Verify the exact suffix EUFD corresponds to the 28-WFQFN package configuration. Confirm that the TRPBF designation indicates tape and reel packaging suitable for automated surface mount assembly. Ensure compatibility with the required operating temperature range and electrical specifications before finalizing procurement orders.

LED Driver IC Selection Notes

Select this component when input voltage fluctuates significantly relative to the LED string voltage. The buck-boost architecture eliminates the need for complex external circuitry to handle voltage inversion. Consider the 150kHz to 650kHz frequency range for balancing efficiency and passive component size requirements.

LED Driver IC Part Context

This part belongs to the LT8391 family of LED controllers designed for high-efficiency lighting applications. It shares functional similarities with other buck-boost drivers but is distinguished by its specific package type and spread spectrum features. The series targets applications requiring robust current regulation under dynamic input conditions.
