* Drives up to 3 LEDs Current setting resistor Compatible with supply voltage of 3V to 5.5V Power ef.
An external resistor, RSET, controls the output current level. The device can deliver up to 30mA over an input voltage .
The CAT3603 is a charge pump LED driver operating in either 1x (LDO) mode or 1.5x fractional mode regulating current through each of the 3 LED pins. Operation at a constant switching frequency of 1MHz allows the use of very small value ceramic capaci.
