CAT32 Datasheet CMOS White Led Driver

Manufacturer: Catalyst Semiconductor

Overview: CAT32 CMOS White LED Driver.

General Description

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) connected in series and provides the necessary regulated current to control the brightness and the color purity.
