The MAX8610–MAX8613/MAX8611V are highly efficient complete power-supply solutions for digital still cameras (DSCs) and digital video cameras (DVCs). Seven internal-MOSFET DC-DC converters provide up to 95% efficiency and generate all critical power supplies in DSC systems. They also feature True Shutdown™, as well as internal compensation to minimize external component count. One additional converter operates with an external MOSFET for optimum design flexibility. In all, eight converter channels include:
- Synchronous-rectified step-up with True Shutdown.
- Two synchronous-rectified step-down (MAX8611/MAX8613/MAX8611V) or step-up (MAX8610/MAX8612) converters power DSC system, I/O, and AFE blocks.
- Low-VOUT (down to 1V), synchronous-rectified step-down to power a DSP core.
- High-output-voltage step-up for CCD bias.
- Transformerless inverter for negative CCD bias.
- High-output-voltage step-up for white LEDs, OLED display, or other output.
- Auxiliary DC-DC boost (MAX8611/MAX8610/MAX8611V) or inverting (MAX8612/MAX8613) controller.
