This document by Denisa Stefan and Cornel Rotaru, applications engineers with Catalyst Semiconductor, describes the CAT3612EVAL1 evaluation/demonstration board for Catalyst's CAT3612, a 300mA flash LED driver with 1-wire interface. The functionality and major parameters of the CAT3612 can be evaluated with the CAT3612EVAL1 board. The CAT3612 is a 2-channel charge pump that has been designed to provide a regulated output current up to 150mA per channel. The device is operating in either 1x (LDO) mode, or 1.5x mode and it is suitable for driving with high efficiency one or two flash LEDs. The programmable current and dimming control of LEDs are achieved using a 1-wire interface. The user can set the current from 150mA down to 0mA with approximately 5mA resolution, by toggling the EN/DIM input. Detailed description and electrical characteristics are in the CAT3612 data sheet.
