CAT3604 driver equivalent, 4-channel regulated charge pump white led driver.
An external resistor RSET controls the output current level. LED currents of up to 30 mA are supported over a range of .
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 1 MHz typical allows the use of very small value ceramic capacitors.
