8-Channel PMICs for

Digital Camera Power Supplies

General Description

Features

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:

♦ 95% Efficient Synchronous-Rectified DC-DCs

♦ 90% Efficient Boost-Buck Operation

♦ 85% Efficient DC-DCs for CCD, LCD, WLED,

and/or OLED

♦ Auxiliary Power for Motors

(MAX8610/MAX8611/MAX8611V)

♦ Internal Compensation

♦ True Shutdown Step-Up Converters

♦ Overload Protection

•

Synchronous-rectified step-up with True Shutdown.

♦ Soft-Start for Controlled Startup Current

♦ Low-Dropout (100% Duty Cycle) Step-Downs

♦ Regulated Current for Up to 6 White LEDS

♦ Open-LED Overvoltage Protection

♦ Transformerless Inverting Converter for CCD

♦ Adjustable 1MHz to 2MHz Switching Frequency

♦ 3% Frequency Accuracy

Two synchronous-rectified step-down (MAX8611/

MAX8613/MAX8611V) or step-up (MAX8610/

MAX8612) converters power DSC system, I/O, and

AFE blocks.

•

Low-V

(down to 1V), synchronous-rectified

OUT

step-down to power a DSP core.

•

High-output-voltage step-up for CCD bias.

Transformerless inverter for negative CCD bias.

♦ 1µA Shutdown Supply Current

High-output-voltage step-up for white LEDs, OLED

display, or other output.

♦ CCD Voltage Sequencing

♦ Voltage Tracking for Core and Logic

(MAX8611/MAX8613/MAX8611V)

♦ Compact 48-Pin, 6mm x 6mm Thin QFN Package

•

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.
