Description
The 20A Digital MicroDLynx TM 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
IN
= 3Vdc-14.4Vdc) and provide a precisely regulated output voltage
from 0.6Vdc to 5.5Vdc, programmable via an external resistor and PMBus TM control. Features include a digital interface using the
PMBus TM protocol, remote On/Off, adjustable output voltage, over current and over temperature protection. The PMBus TM #
interface supports a range of commands to both control and monitor the module. The module also includes the Tunable Loop TM
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.
