8-Channel PMICs for Digital Camera Power Supplies
General DescriptionThe MAX8610–MAX8613/MAX8611V are highly efficient
complete power-supply solutions for digital still cam-
eras (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.
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.
