These modules operate off an input voltage from 2.7 to 4.0Vdc and provide an output voltage that is programmable from 0.8 to 2.0Vdc. They have a sequencing feature that enables designers to implement various types of output voltage sequencing when powering multiple modules on the board. Additional features include remote On/Off, adjustable output voltage, remote sense, over current, over temperature protection and active current sharing between modules. * UL is a registered trademark of Underwriters Laboratories, Inc. † ‡ CSA is a registered trademark of Canadian Standards Association.

These are absolute stress ratings only, functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect the device reliability.
