MAX868EUB+ Description

Short technical summary and product information.

The MAX868EUB+ is an inverting charge pump DC-DC converter from Analog Devices. It is designed to generate a regulated negative voltage up to -2 times the input voltage, from a positive input range of 1.8V to 5.5V. This device utilizes a pulse-frequency-modulation (PFM) control scheme and operates at switching frequencies between 270kHz and 630kHz.

 

Key electrical specifications include an output current capability of up to 30mA and a quiescent supply current of 30µA. The MAX868EUB+ requires only four external capacitors and two resistors for output voltage regulation, eliminating the need for inductors. It features a logic-controlled shutdown mode with a low 0.1µA current.

 

The component is housed in an ultra-small 10-pin µMAX package, measuring only 1.11mm high and occupying minimal board space. This makes it suitable for compact battery-operated equipment. The operating temperature range is -40°C to 85°C.

 

Applications for the MAX868EUB+ include small LCD panels, cell phones, cordless phones, camcorders, handy-terminals, PDAs, medical instruments, and other battery-powered devices requiring a negative voltage rail.
