Seven internal-MOSFET DC-DC converters provide up to 95% efficiency and generate all critical power supplies in DSC systems. They also feature True ShutdownTM, 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-V OUT (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. * * * * * The MAX8611/MAX8613/MAX8611V operate in 1-cell lithium-ion (Li+) and dual-battery (Li+ and 2 AA) designs. The MAX8610/MAX8612 operate in 2 AA designs.
