Overview
| Topology | Buck Converter |
| Input voltage | 3.8-36 V |
| Output 1 | 3 A |
| IC revision | 1.0 |
Description
The EV9430-B-03A Evaluation Board is designed to demonstrate the capabilities of SCT9430 what are EMI friendly synchronous buck converters with up to 36V wide input voltage range. which fully integrates an 80mΩ high-side MOSFET and a 42mΩ low-side MOSFET to provide high efficiency step-down DC-DC conversion.The SCT9430 is an Electromagnetic Interference (EMI) friendly buck converter with implementing optimized design for EMI reduction. The converter has proprietary designed gate driver scheme to resist switching node ringing without sacrificing MOSFET turn-on and turn-off time, which further erases high frequency radiation EMI noise caused by the MOSFETs hard switching.The device is available in a low- profile TSOT23-6L package.This user's guide describes the characteristics,operation and the use of the EV9430-B-03A Evaluation Module including EVM specifications, recommended test setup, test result, schematic diagram, bill of materials, and the board layout.
