CAT3603 3-Channel LED Driver

CAT3603 Description

CAT3603 3-Channel LED Driver in 3 x 3 mm Package .
The CAT3603 is a charge pump LED driver operating in either 1x (LDO) mode or 1.

CAT3603 Features

* Drives up to 3 LEDs
* Current Setting Resistor
* Compatible with Supply Voltage of 3 V to 5.5 V
* Power Efficiency up to 91%
* Output Current up to 30 mA per LED
* Fractional Pump 1x/1.5x
* Low Noise Input Ripple
* Fixed High Frequenc

CAT3603 Applications

* An external resistor, RSET, controls the output current level. The device can deliver up to 30 mA over an input voltage supply range from 3 V to 5.5 V, making it ideal for battery
* powered applications. LED dimming can be accomplished using several methods; using a DC voltage to set the RSE
