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 FETs
? Main DC-to-DC converter with on-chip FETs, config-
urable to step either up or down
? Step-down core DC-to-DC converter with on-chip
FETs
? DC-to-DC controller for white LEDs or other output
? Extra DC-to-DC controller (typically for LCD); two
extra controllers on the MAX1566
? Transformerless inverting DC-to-DC controller (typi-
cally for negative CCD bias) on the MAX1567
Features
? 95% Efficient Step-Up DC-to-DC Converter
? 0.7V Minimum Input Voltage
? Main DC-to-DC Configurable as Either Step-Up or
Step-Down
? Combine Step-Up and Step-Down for 90%
Efficient Boost-Buck
? 95% Efficient Step-Down for DSP Core
? Regulate LED Current for Four, Six, or More LEDs
? Open LED Overvoltage Protection
? Transformerless Inverting Controller (MAX1567)
? Three Extra PWM Controllers (Two on the
MAX1567)
? Up to 1MHz Operating Frequency
? 1μA Shutdown Mode
? Soft-Start and Overload Protection
? Compact 40-Pin 6mm x 6mm Thin QFN Package
Ordering Information
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.
