CAT3603 Datasheet - ON Semiconductor

CAT3603 - 3-Channel LED Driver

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
