Small, High-Efficiency, Five-Channel  
Digital Still Camera Power Supply  
General Description  
Features  
The MAX1565 provides a complete power-supply solution  
for digital still and video cameras through the integration  
of ultra-high-efficiency step-up/step-down DC-to-DC con-  
verters along with three auxiliary step-up controllers. The  
MAX1565 is targeted for applications that use either 2 or  
3 alkaline or NiMH batteries as well as those using a  
single lithium-ion (Li+) battery.  
ꢀ Step-Up DC-to-DC Converter

ꢀ Step-Down DC-to-DC Converter  
Operate from Battery for 95% Efficient Buck  
Combine with Step-Up for 90% Efficient Buck-  
Boost  
The step-up DC-to-DC converter accepts inputs from  
0.7V to 5.5V and regulates a resistor-adjustable output  
from 2.7V to 5.5V. It uses internal MOSFETs to achieve  
95% efficiency. Adjustable operating frequency facili-  
tates design for optimum size, cost, and efficiency.  
Adjustable Output Down to 1.25V  
ꢀ Three Auxiliary PWM Controllers  
ꢀ Up to 1MHz Operating Frequency  
ꢀ 1µA Shutdown Mode  
The step-down DC-to-DC converter can produce output  
voltages as low as 1.25V and also utilizes internal  
MOSFETs to achieve 95% efficiency. An internal soft-  
start ramp minimizes surge current from the battery.  
The converter can operate from the step-up output pro-  
viding buck-boost capability with up to 90% compound  
efficiency, or it can run directly from the battery if buck-  
boost operation is not needed.  
ꢀ Internal Soft-Start Control  
ꢀ Overload Protection  
ꢀ Compact 32-Pin, 5mm x 5mm Thin QFN Package  
The MAX1565 features auxiliary step-up controllers that  
power CCD, LCD, motor actuator, and backlight cir-  
cuits. The device also features low-cost expandability  
by supplying power, an oscillator signal, and a refer-  
ence to the MAX1801 SOT23 slave controller that sup-  
ports step-up, SEPIC, and flyback configurations.
