True Shutdown is a trademark of Maxim Integrated Products, Inc.

The 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:

•

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.

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

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/
