LM3590
Series White LED Driver
General Description
The LM3590 is a White LED constant current driver capable
of supplying up to 3 White LEDs connected in series with
20mA. This device operates over a wide 6V-12.6V input
voltage range. The output can accomodate LEDs with a
combined forward voltage of up to 11.5V, from a 12V input
supply. The LED drive current is programmed by using an
external resistor on the I
SET
pin.
LED brightness can be linearly varied up to the programmed
LED current by applying a Pulse Width Modulated (PWM)
signal to the EN pin of the device. The LED output current of
the LM3590 is tightly controlled over temperature and volt-
age. LED Current matching is guaranteed due to the series
configuration of the LEDs. The series topology also simpli-
fies the connection between the White LEDs in the display
module and the LM3590 since only one connection is re-
quired.
The LM3590 typically draws only 50μAwhen operating in the
no-load condition and draws less than 0.1μA when the de-
vice is shut down.
The LM3590 is available in a small 5-pin SOT23 package.
