LT3763HFE#PBF

LED Driver IC Overview

The LT3763HFE#PBF is a fixed-frequency, synchronous step-down DC/DC controller designed for high-current LED driver applications. It regulates output currents up to 20A with precision average current mode control. The device operates within a supply voltage range of 6V to 60V and supports an output voltage of up to 55V. Switching frequency is adjustable from 200kHz to 1MHz. It features PWM dimming capability and functions within a junction temperature range of -40°C to 150°C. The component is housed in a 28-TSSOP-EP package.

LED Driver IC Procurement Notes

Verify the specific suffix HFE against the official Analog Devices datasheet to confirm the operating temperature grade and package variant. Ensure the design accounts for the exposed pad thermal requirements associated with the 28-TSSOP-EP package. Cross-reference the latest revision history for any material or epoxy changes that may impact long-term reliability or assembly processes.

LED Driver IC Selection Notes

Select this controller when input voltages reach up to 60V and output currents exceed standard IC limits. The synchronous architecture reduces external component count compared to non-synchronous alternatives. Verify that the required switching frequency falls within the 200kHz to 1MHz range. Ensure the application demands precise current regulation suitable for average current mode control rather than simple voltage regulation.

LED Driver IC Part Context

This part belongs to the LT3763 series, which includes variants like LT3763IFE#PBF. The HFE suffix typically denotes a specific temperature rating or package configuration distinct from other series members. The series is engineered for robust performance in demanding LED driving environments requiring high efficiency and thermal stability.

LED Driver IC Replacement Considerations

LT3763IFE#PBF is a documented alternative within the same product family. Verify if the temperature range and package thermal characteristics match the specific application requirements before substitution.
