Description

The GigaTLynxTM series of power modules are non-isolated dc-dc converters that can deliver up to 50A of output
current. These modules operate over a wide range of input voltage (V
regulated output voltage from 0.7Vdc to 2.0Vdc, programmable via an external resistor. Features include remote
On/Off, adjustable output voltage, over current and over temperature protection, output voltage sequencing and
paralleling. The Ruggedized version (-D) is capable of operation up to 105°C and withstand high levels of shock
and vibration. The Tunable Loop

TM

feature, 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 surface mount, fast acting fuse (ie. Littelfuse 456030 series) with a maximum rating of 30 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.
