Description

3.8V-40V Vin, 3.5A High Efficiency Synchronous Step-down DCDC Converter Evaluation Board.The EV2430-B-03A Evaluation Board is designed to demonstrate the capabilities of SCT2430, SCT2431, SCT2432 and SCT2439, high efficiency fully integrated synchronous step-down DCDC converter supporting up to 3.5A continuous output current from an input source from 3.8V to 40V. The SCT2430 SCT2432 and SCT2439 offer adjustable switching frequency ranging from 100kHz to 2.2MHz with internal 4ms soft-start, which provides flexibility to optimize either efficiency or external component size. The SCT2431 features adjustable soft-start with fixed 570KHz switching frequency. Both devices are available in an easy-soldering 8-pin ESOP package.
