Description

The 12V TLynx

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

= 4.5Vdc-14Vdc) and provide a precisely

regulated output voltage from 0.69Vdc to 5.5Vdc, programmable via an external resistor. Features include

frequency synchronization, remote On/Off, adjustable output voltage, over current and temperature protection,

power good and output voltage sequencing. The Ruggedized version (-D) is capable of operation up to 105°C and

withstand high levels of shock and vibration. 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.

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 20 A (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.
