●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 techniques. 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 brightness 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 TI"s WSON-10 package.
