EUP3595
Parallel White-LED Driver
DESCRIPTION
The EUP3595 is a parallel white-LED driver with four
matched current outputs. 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.
EUP3595 typically draws 0.01µA when placed in
shutdown, and 180µA 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 PWM techniques or by
adding a DC voltage. A PWM signal can be applied to
the EN/PWM pin to vary the perceived brightness of the
LED.
The EUP3595 uses an active-high enable level. The
EUP3595 is available in TDFN-8 and TSSOP-8 package.
