Kinetic Technology KTB8331 | Demoboard KTB8331DEDAA-MMEV02

Description

KTB8331 is a precision adaptive-on-time (AOT) buck switching regulator with class-leading accuracy, transient response, efficiency, and solution size optimized for mobile and non-mobile application. The KTB8331 Evaluation (EVAL) board is used to demonstrate the KTB8331 Buck regulator detailed functionality, performance, and the PCB layout. The kit includes a fully assembled and tested KTB8331 EVAL board, I2C Adaptor, connecting cable, and a printed copy of the Quick Start Guide.
