CAT32 Datasheet - Catalyst Semiconductor

CAT32 CMOS White LED Driver

The CAT32 is a DC/DC step up converter that delivers a regulated output current. Operation at a constant switching frequency of 1.2MHz allows the device to be used with very small value external inductor and ceramic capacitors. The CAT32 is targeted to drive multiple white lightemitting diodes (LEDs.
