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.
