LвЂ‰DESIGN IDEAS White LED Driver with Output
Disconnect and 1-Wire
by Ahmed Hashim
Current Programming
Introduction
The LT3593 is designed to drive up to
ten white LEDs in series from a single
lithium-ion cell, ensuring matched
LED current and eliminating the need
for ballast resistors. The LT3593 internally compensated step-up DC/DC
converter switches at 1MHz so that
it can be used with tiny, low profile
external components.
The LT3593 features an internal
5-bit DAC, allowing the LED current
to be programmed using only one
pin. The device features true output
disconnect in shutdown as well as a
unique high side current sense allowing it to function as a вЂњ1-wireвЂќ current
source where the low side of the LEDs
can be returned to ground anywhere.
A typical application schematic along
with expected efficiency can be seen …
