Description
The 40A Analog Mega DLynx
power modules are non-isolated dc-dc converters that can deliver up to 40A of
output current. These modules operate over a wide range of input voltage (V
IN
= 4.5Vdc-14.4Vdc) and provide a
precisely regulated output voltage from 0.6Vdc to 2.0Vdc, programmable via an external resistor. Features include
remote On/Off, adjustable output voltage, over current and overtemperature protection. The module also includes
TM
the Tunable Loop feature that 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.
