MAX8680 - 7-Channel DSC PMIC

General Description

The MAX8680 highly efficient complete power-supply solution is designed for digital still cameras (DSCs) and digital video cameras (DVCs).

The device integrates seven on-chip power MOSFET DC-DC converters with up to 95% efficiency to power all critical power supplies in DSC systems.

Key Features

  • True Shutdown™, as well as internal compensation to minimize external component count. The seven DC-DC converter outputs are:.
  • Step-up synchronous-rectified DC-DC converter (SU). The MAX8680 is bootstrapped from VSU.
  • MAIN synchronous-rectified step-down DC-DC converter (M) for DSP I/O supply voltage. DDRZ synchronous-rectified step-down DC-DC converter (Z) for DSP DDR supply voltage. Low-voltage (down to 1V) synchronous-rectified step-down DC-DC converter (.
