Product Overview

The LT3592EDDB#TRMPBF is a fixed frequency step-down DC/DC Converter designed to operate as a constant-current source. An external sense resistor monitors the output current allowing accurate current regulation, ideal for driving high current LEDs. The output current can be dimmed by a factor of 10 using an external signal for night-time brake lights. The high switching frequency offers several advantages by permitting the use of a small inductor and small ceramic capacitors. The constant switching frequency combined with low-impedance ceramic capacitors result in low, predictable output ripple. A wide input voltage range of 3.6 to 36V makes the LT3592 useful in a variety of applications. Current mode PWM architecture provides fast transient response and cycle-by-cycle current limiting. Thermal shutdown provides additional protection.
  • Shorted and open LED protected
  • Internal switch current sense resistor
  • External resistor programs LED current, pin selects 10:1 ratio
  • Catch diode current sense to prevent runaway at high VIN
