The EV2450-B-03A Evaluation Board is designed to demonstrate the capabilities of SCT2450 and SCT2451, high efficiency fully integrated synchronous step-down DCDC converter supporting up to 5A continuous output current from an input source from 3.8V to 36V. The SCT2450 offers adjustable switching frequency ranging from 100kHz to 1.1MHz with internal 4ms soft-start, which provides flexibility to optimize either efficiency or external component size. The SCT2451 features adjustable soft-start with fixed 570KHz switching frequency. Both devices are available in an easy-soldering 8-pin ESOP package. This user's guide describes the characteristics, operation and the use of the EV2450-B-03A Evaluation Module including EVM specifications, recommended test setup, test result, schematic diagram, bill of materials, and the board layout.
