CAT37 Datasheet - ON Semiconductor

CAT37 CMOS White LED Driver

The CAT37 is a DC/DC step up converter that delivers a regulated output current. Operation at a constant switching frequency of 1.2 MHz allows the device to be used with very small value external inductor and ceramic capacitors. The CAT37 is targeted to drive multiple white light *emitting di.
