LINEAR LTC3593 Manual
The LT3593 is an internally compensated step-up DC/DC converter that switches at 1MHz. It features an internal 5-bit DAC allowing LED current to be programmed using only one pin, eliminating the need for ballast resistors. The device supports true output disconnect in shutdown and functions as a '1-wire' current source.

Questions answered in these manuals
What is the maximum number of white LEDs this driver can power in series?
The LT3593 is designed to drive up to ten white LEDs in series from a single lithium-ion cell.
From: LINEAR LTC3593 Manual
What is the full-scale LED current when using the 1-Wire programming feature?
The full-scale current for the programmed LED output is 20mA.
From: LINEAR LTC3593 Manual
What type of capacitors should be used with the LT3593?
Use only X5R or X7R ceramic capacitors for the input and output because they retain capacitance over a wide voltage and temperature range.
Which inductor is recommended for typical LT3593 applications?
A 10 µH inductor, such as the Murata LOH43CN100, is recommended for most LT3593 designs.
