General Description
Features
The MAX8614A/MAX8614B dual-output step-up DC-DC
converters generate both a positive and negative sup-
ply 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 pow-
ering 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 out-
put down to 16V below the input voltage. The
MAX8614B has a higher current limit than the
MAX8614A. Both devices operate at a fixed 1MHz fre-
quency 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
