These modules operate over a wide range of input voltage (V = 4.5Vdc-14Vdc) and provide a precisely IN regulated output voltage from 0.69Vdc to 5.5Vdc, programmable via an external resistor. Two new features TM added with this family of products are frequency synchronization and the Tunable Loop . Other features include remote On/Off, adjustable output voltage, over current and over temperature protection, power good and output TM voltage sequencing. The Tunable Loop allows the user to optimize the dynamic response of the converter to match the load with reduced amount of output capacitance leading to savings on cost and PWB area.

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.

An input line fuse must be used in application. This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part of sophisticated 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 fast-acting fuse with a maximum rating of 20A. 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 manufacturers data sheet for further information. Note: Unless otherwise indicated, specifications apply over all operating input voltage, resistive load, and temperature conditions.
