5-Channel Slim DSC Power Supplies

General Description

Features

The MAX1584/MAX1585 provide a complete power-

supply solution for slim digital cameras. They improve

performance, component count, and size compared to

conventional multichannel controllers in 2-cell AA, 1-cell

Li+, and dual-battery designs. On-chip MOSFETs pro-

vide up to 95% efficiency for critical power supplies,

while additional channels operate with external FETs for

optimum design flexibility. This optimizes overall effi-

ciency and cost, while also reducing board space.

90% Efficient Boost-Buck with Step-Up

ꢀ Three Auxiliary PWM DC-DC Controllers

ꢀ No Transformers (MAX1585)

ꢀ Up to 1MHz Operating Frequency

ꢀ 1mA Shutdown Mode

The MAX1584/MAX1585 include 5 high-efficiency DC-

DC conversion channels:

• Step-up DC-DC converter with on-chip FETs

• Step-down DC-DC converter with on-chip FETs

ꢀ Internal Soft-Start Control

ꢀ Overload Protection

• Three PWM DC-DC controllers for CCD, LCD, LED,

or other functions

ꢀ Compact 32-Pin Thin QFN Package (5mm x 5mm)

The step-down DC-DC converter can operate directly

from the battery or from the step-up output, providing

boost-buck capability with a compound efficiency of up

to 90%. Both devices include three PWM DC-DC con-

trollers: the MAX1584 includes two step-up controllers

and one step-down controller, while the MAX1585

includes one step-up controller, one inverting controller,

and one step-down controller. All DC-DC channels

operate at one fixed frequency—settable from 100kHz

to 1MHz—to optimize size, cost, and efficiency. Other

features include soft-start, power-OK outputs, and over-

load protection. The MAX1584/MAX1585 are available

in space-saving, 32-pin thin QFN packages. An evalua-

tion kit is available to expedite designs.
