Overview

CAT3603 3-Channel LED Driver in 3 x 3 mm Package Description 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 1 MHz allows the use of very small value ceramic capacitors.
The CAT3603 drives 3 white LEDs in parallel and provides tightly matched regulated current to achieve uniform brightness in LCD backlighting 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 acco...
