Step-up-down Dc-dc Converts

The ML1565 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 ML1565 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 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 facilitates design for optimum size, cost, and efficiency. 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 softstart ramp minimizes surge current form the battery. The converter CAN operate from the Step-up output providing buck-boost capability with up to 90% compound efficiency, or it CAN run directly from the battery if buck-boost operation is not needed. The ML1565 features auxiliary Step-up controllers that power CCD LCD motor actuator, and backlight circuits. The ML1565 is available in a space-saving QFN-32 thin package.
