LT8393EFE#TRPBF

LED Driver IC Overview

The LT8393EFE#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 range up to 60V and an output voltage up to 100V. It utilizes a proprietary peak buck-peak boost current mode control scheme with a switch frequency adjustable from 350kHz to 2MHz. Packaged in a 28-lead TSSOP, it is designed for high-efficiency LED lighting applications requiring versatile power management.

LED Driver IC Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status and lead time requirements directly with authorized distributors or the manufacturer, as supply availability may vary. Ensure the ordering information matches the specific functional variant required for your design.

LED Driver IC Selection Notes

Select this controller when the LED string voltage may exceed, fall below, or match the source voltage. The wide operating frequency range permits trade-offs between magnetic component size and efficiency. Verify that the thermal performance of the TSSOP-28 package meets the application's heat dissipation requirements under maximum load conditions.
