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.

A highly inductive source can affect the stability of the module. An input capacitance must be placed directly adjacent to the input pin of the module, to minimize input ripple voltage and ensure module stability.

Optimal performance of the module can be achieved by using the Tunable LoopTM feature described later in this data sheet.
