Description
The EV1270-B-01A Evaluation Board is designed to demonstrate the capabilities of SCT1270, a high efficiency fully integrated synchronous boost converter. It offers a very compact solution to achieve up to small size power solution for portable equipment. 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 SCT1270 is available in a spacesaving 11-pin QFN 2mmx2.5mm package.This user's guide describes the characteristics, operation and the use of the EV1270-B-01A Evaluation Module including EVM specifications, recommended test setup, test result, schematicdiagram, bill of materials, and the board layout.
