The LT3593 is a step-up DC/DC converter designed to drive up to ten 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 a 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. The LT3593 is available in the 6-lead DFN (2mm × 2mm) as well as the 6-lead SOT-23 packages.
