This document by Denisa Stefan and Cornel Rotaru, applications engineers with Catalyst Semiconductor, describes the CAT3636DB1 evaluation/demonstration board for Catalyst's CAT3636 6-channel quad-mode fractional LED driver. The functionality and major parameters of the CAT3636 can be evaluated with the CAT3636DB1 board. The CAT3636 is a 6-channel charge pump that has been designed to drive with high efficiency up to 6 LEDs connected in parallel. The device can drive three groups of two LEDs. Each group can be configured with independent LED current of up to 32mA max per channel through the 1-wire serial interface. The CAT3636 is operating in either 1x mode (LDO), 1.33x, 1.5x, or 2x mode and provides tightly matched regulated current through the six LED outputs. Each bank of LEDs can be also turned off/on independently through the 1-wire digital interface. Detailed descriptions and electrical characteristics are in the CAT3636 data sheet.
