CAT4139 pdf,datasheet22V High Current Boost White LED DriverThe CAT4139 is a DC/DC step-up converter that delivers anaccurate constant current ideal for driving LEDs. Operation at a fixedswitching frequency of 1 MHz allows the device to be used with smallvalue external ceramic capacitors and inductor. LEDs connected inseries are driven with a regulated current set by the external resistorR1. The CAT4139 is ideal for driving parallel strings of up to fivewhite LEDs in series or up to 22 V.
