Product Details

The MAX8680 evaluation kit (EV kit) is a fully assembled and tested printed-circuit board (PCB) that evaluates the MAX8680 power-management IC. The MAX8680 accepts an input from 2.7V to 5.5V and provides a complete power-supply solution for digital still cameras (DSCs) and digital video cameras (DVCs). It integrates seven on-chip power MOSFET DC-DC converters, with up to 95% efficiency to power all critical power supplies in DSC systems. All step-up converters also feature True Shutdown™, as well as internal compensation, to minimize external component count.

Applications

  • DSCs and DVCs
  • GPS Navigation Systems
  • PDAs and Portable Media Players
