Datasheet EUP3595 DatasheetEUP3595 Datasheet (PDF)

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. Brig.

Parallel White-LED Driver

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 www.DataSheet4U.com 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.
