MAX1565ETJ Datasheet

PMIC Solutions


The MAX1565ETJ 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 converters along with three auxiliary step-up controllers. The MAX1565ETJ 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.The MAX1565ETJ features auxiliary step-up controllers that power CCD, LCD, motor actuator, and backlight circuits.The device also features low-cost expandability by supplying power, an oscillator signal, and a reference to the MAX1801 SOT23 slave controller that supports step-up, SEPIC, and flyback configurations. MAX1565ETJ Features • Step-Up DC-to-DC Converter 95% Efficient 3.3V (Fixed) or 2.7V to 5.5V (Adjustable) Output Voltage• Step-Down DC-to-DC Converter Operate from Battery for 95% Efficient Buck Combine with Step-Up for 90% Efficient Buck-Boost Adjustable Output Down to 1.25V• Three Auxiliary PWM Controllers• Up to 1MHz Operating Frequency• 1μA Shutdown Mode• Internal Soft-Start Control• Overload Protection• Compact 32-Pin, 5mm x 5mm Thin QFN Package MAX1565ETJ Applications • Digital Still Cameras• Digital Video Cameras• PDAs
