Description

The EV2435-B-01A Evaluation Board is designed todemonstrate the capabilities of SCT2435 high efficiency fully integrated synchronous step-down DCDC converter supporting up to 3A continuous output current from an input source from 3.8V to 40V.The SCT2435 offer adjustable switching frequency ranging from 100kHz to 2.2MHz with internal 2ms soft-start, which provides flexibility to optimize either efficiency or external component size,The devices,adopting the peak current mode control, supports the Pulse Skipping Modulation (PSM) with typical 25uA low quiescent current which assists the converter on achieving high efficiency at light load or standby condition. The device is available in an 8-pin thermally enhanced SOP-8 package.This user's guide describes the characteristics,operation and the use of the EV2435-B-01A Evaluation Module including EVM specifications, recommended test setup, test result, schematic diagram, bill of materials, and the board layout.
