Product Details

The MAX8614A/MAX8614B dual-output step-up DC-DC converters generate both a positive and negative supply voltage that are each independently regulated. The positive output delivers up to 50mA while the inverter supplies up to 100mA with input voltages between 2.7V and 5.5V. The MAX8614A/MAX8614B are ideal for powering CCD imaging devices and displays in digital cameras and other portable equipment.

The MAX8614A/MAX8614B generate an adjustable positive output voltage up to +24V and a negative output down to 16V below the input voltage. The MAX8614B has a higher current limit than the MAX8614A. Both devices operate at a fixed 1MHz frequency to ease noise filtering in sensitive applications and to reduce external component size.

Additional features include pin-selectable power-on sequencing for use with a wide variety of CCDs, True Shutdown™, overload protection, fault flag, and internal soft-start with controlled inrush current.

The MAX8614A/MAX8614B are available in a spacesaving 3mm x 3mm 14-pin TDFN package and are specified over the -40°C to +85°C extended temperature range.
