MAX1566ETL
0.7 to 5.5 V, six-channel, high-efficiency, digital camera power supplies
General Description
The MAX1566/MAX1567 provide a complete power-
supply solution for digital cameras. They improve perfor-
mance, component count, and size compared to con-
ventional multichannel controllers in 2-cell AA,
1-cell lithium-ion (Li+), and dual-battery designs. On-chip
MOSFETs provide up to 95% efficiency for critical power
supplies, while additional channels operate with external
FETs for optimum design flexibility. This optimizes overall
efficiency and cost, while also reducing board space.
The MAX1566/MAX1567 include six high-efficiency DC-
to-DC conversion channels:Step-up DC-to-DC converter with on-chip power FETsMain DC-to-DC converter with on-chip FETs, config-
urable to step eitherup or downStep-down core DC-to-DC converter with on-chip
FETsDC-to-DC controller for white LEDs or other outputExtra DC-to-DC controller (typically for LCD); two
extra controllers on the MAX1566Transformerless inverting DC-to-DC controller (typi-
cally for negative CCD bias) on the MAX1567
All DC-to-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 overload protection. The MAX1566/
MAX1567 are available in space-saving 40-pin thin QFN
packages. An evaluation kit is available to expedite
designs.

ABSOLUTE MAXIMUM RATINGS

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

ELECTRICAL CHARACTERISTICS
Note 1:
LXSU has internal clamp diodes to PVSU and PGSU, LXM has internal clamp diodes to PVM and PGM, and LXSD has inter-
nal clamp diodes to PVSD and PGSD. Applications that forward bias these diodes should take care not to exceed the
devices’ power dissipation limits.
