These modules provide a precisely regulated output voltage programmable via external resistor TM from 0.75Vdc to 2.0Vdc over a wide range of input voltage (VIN = 2.4 – 3.63Vdc). Austin SuperLynx II has a TM sequencing feature, EZ-SEQUENCE that enable designers to implement simultaneous or ratiometric startup of multiple rails on board. Their open-frame construction and small footprint enable designers to develop cost- and space-efficient solutions. In addition to sequencing, standard features include remote On/Off, remote sense, programmable output voltage, over current and over temperature protection. * 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.

This power module can be used in a wide variety of applications, ranging from simple standalone operation to being part of complex power architecture. To preserve maximum flexibility, internal fusing is not included. This power module meets all safety agency requirements without presence of an input fuse. However, to achieve maximum safety and system protection, an input line fuse may be used. Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data sheet for further information.
