Product Overview

The LT3593ES6#TRMPBF is a step-up DC/DC Converter designed to drive up to 10 white LEDs in series from a Li-ion cell. Series connection of the LEDs provides identical LED currents and eliminates the need for ballast resistors. The device features unique high-side LED current sense that enables the part to function as a one wire current source where the low-side of the LED string can be returned to ground anywhere. Additional features include output disconnect in shutdown, open LED protection and 1-pin shutdown/LED current control. The CTRL pin is toggled to adjust the LED current via an internal counter and a 5-bit DAC. The LT3593 switches at 1MHz, allowing the use of tiny external components. Constant frequency switching results in low input noise and a small output capacitor.
  • One pin shutdown and current programming
  • LEDs disconnected in shutdown
  • ±5% Output current accuracy at full scale
  • Requires only 1µF output capacitor
  • 3µA Low shutdown current
