The LT3592EDDB#TRPBF by Analog Devices Inc. is a fixed-frequency step-down DC/DC converter designed to function as a constant-current source, ideal for driving high-current LEDs. It features a wide input voltage range from 3.6V to 36V, making it suitable for various applications.
The device allows for accurate current regulation through an external sense resistor and supports dimming by a factor of 10 using an external signal. The switching frequency is adjustable from 400kHz to 2.2MHz, enabling the use of small inductors and ceramic capacitors, thus saving space and cost. The constant switching frequency and low-impedance ceramic capacitors result in low, predictable output ripple.
Key features include protection against shorted and open LEDs, internal switch current sense, and catch diode current sense to prevent runaway conditions at high VIN. The LT3592EDDB#TRPBF is available in a small, thermally enhanced 10-lead DFN (3x2mm) package and an MSOP-10 package. Its applications include automotive signal lighting, industrial lighting, and constant-current/constant-voltage supplies.
