CAT3604 Datasheet (Catalyst Semiconductor) - 4-Channel Regulated Charge Pump White LED Driver

CAT3604, 4-Channel Regulated Charge Pump White LED Driver

The CAT3604 is a charge pump operating in either 1x (LDO) mode or 1.5x fractional mode regulating current through each of the 4 LED pins.

Operation at a fixed high frequency of 1MHz typical allows the use of very small value ceramic capacitors.

The CAT3604 drives white light-emitting diodes (LEDs) c
