Description
Austin SuperLynx II SIP power modules are non-isolated dc-dc converters that can deliver up to 16A of output current with full load efficiency of 95% at 3.3V output. These modules provide a precisely regulated output voltage programmable via external resistor from 0.75Vdc to 3.3Vdc over a wide range of input voltage (VIN = 2.4 – 5.5Vdc). TM TM Austin SuperLynx II has a sequencing feature, EZ-SEQUENCE that enable designers to implement various types of output voltage sequencing when powering multiple modules 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.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. 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.

CAUTION: This power module is not internally fused. An input line fuse must always be used.
This power module can be used in a wide variety of applications, ranging from simple standalone operation to being part of a complex power architecture. To preserve maximum flexibility, internal fusing is not included, however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a 20A, fast-acting, glass type fuse rated for 32V (see Safety Considerations section). 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.
