MAX868EUB Description

Short technical summary and product information.

The MAX868EUB is an inverting charge pump IC designed by Analog Devices / Maxim Integrated. It offers a low-cost and compact solution for generating a regulated negative voltage from a positive input voltage ranging from 1.8V to 5.5V. This device utilizes a pulse-frequency-modulation (PFM) control scheme and operates at an on-demand switching frequency of up to 450kHz.

 

The MAX868EUB requires only four external capacitors and two resistors for output voltage regulation, eliminating the need for inductors. It can deliver up to 30mA of output current with a quiescent supply current of 30µA. The device features a logic-controlled shutdown with a current draw of 0.1µA.

 

This charge pump is housed in an ultra-small, 10-pin µMAX package, measuring only 1.11mm high and occupying half the board area of a standard 8-pin SO package. Its compact size and surface-mount capability make it suitable for space-constrained applications.

 

Applications include small LCD panels, cell phones, cordless phones, camcorders, handy-terminals, PDAs, medical instruments, and other battery-operated equipment.
