LM3595
Parallel White-LED Driver
General Description
The LM3595 is a parallel white-LED driver that is capable of
driving four white LEDs. It can supply a total output current of
100mA over an input voltage range of 3.0V to 5.5V. The
amount of constant current sourced to the outputs is user
selectable using one external sense resistor.
LM3595 typically draws 0.03μA when placed in shutdown,
and 200μA when operating in the no-load condition. If any of
the outputs are not used, leave the pin(s) unconnected.
Brightness can be controlled by both analog and PWM tech-
niques. A voltage between 0V and 3V may be applied to the
BRGT pin to vary the current. Output current will linearly
track the voltage applied to the BRGT pin. An active-low
level must be present on the BR-ON pin for analog bright-
ness control to be disabled. Alternatively, a PWM signal can
be applied to the EN pin to vary the perceived brightness of
the LED.
The LM3595 uses an active-high enable level. The LM3595
is available in National’s LLP-10 package.
