Description
The 12V Mega TLynx power modules are non-isolated dc-dc converters that can deliver up to 30A of output
current. These modules operate over a wide range of input voltage (V
IN
= 6Vdc-14Vdc) and provide a precisely
regulated output voltage from 0.8Vdc to 3.63Vdc, programmable via an external resistor. Features include remote
On/Off, adjustable output voltage, over current and over temperature protection, output voltage sequencing and
paralleling with active current sharing (-P 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.
