Description
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.
