to optimize dynamic output

Description

The TLynxTM series of power modules are non-isolated dc-dc converters that can deliver up to 20A of output current. These modules operate over a wide range of input voltage (V output voltage from 0.6Vdc to 3.63Vdc, programmable via an external resistor. Features include remote On/Off, adjustable output voltage, over current and overtemperature protection, and output voltage sequencing (APTH versions). A new feature, the Tunable Loop

TM

, 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.

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 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 (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.
