MAX8680ELT
MAX8680ELT - Brand New Maxim Integrated IC Chips
Credit Card - One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
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. Each converter
also 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
(SD) for DSP core supply voltage.
• High-voltage, step-up DC-DC converter with current regulation and PWM
dimming control (LEDBST) for white LEDs (WLED).
• High-voltage step-up DC-DC converter (CCDBST) for CCD imagers or positive
LCD bias supplies.
• Transformerless inverting DC-DC converter (CCDINV) for CCD imagers or
negative LCD bias supplies.
