The LT®3593 is a step-up DC/DC converter designed to drive up to ten white LEDs in series from a Li-Ion cell.

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.
