概述
Description
LT3467 is a high-efficiency switched‑mode LED driver IC from Analog Devices/Linear Technology that delivers constant-current to LED strings over a wide input range, with built‑in protection features. LT3467EDDB is the evaluation/development board for this IC. It provides a ready-to-use demonstration circuit that includes the LT3467 plus the recommended external parts (inductor, Schottky diode, sense resistor, LED string) and test points. The board lets you set the LED current with a programming resistor and adjust dimming via a control input, enabling quick evaluation of performance, efficiency, regulation stability, and protection behavior. It’s suitable for automotive and general lighting applications. To use it, connect your power supply to VIN, connect the LED string to the LED output, and follow the EDDB guide to set current and dimming while consulting the LT3467 datasheet for detailed specs and layout notes.
