Description

The EV12A2-B-01A Evaluation Board is designed to demonstrate the capabilities of SCT12A2, a high efficiency fully integrated synchronous boost converter. It offers a very compact solution to achieve up to 45W continuous output power over a wide input supply range. The constant off-time peak current-mode operation provides fast transient response and eases loop stabilization. The device features include over-current protection, output over voltage protection and thermal shutdown. The SCT12A2 is available in a space-saving 20-pin DFN 3.5mmx4.5mm package.This user's guide describes the characteristics, operation and the use of the EV12A2-B-01A Evaluation Module including EVM specifications, recommended test setup, test result, schematic diagram, bill of materials, and the board layout.
