General Description
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.
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
Three PWM DC-DC controllers for CCD, LCD, LED,
or other functions
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.
