Description
The 20A Digital Micro DLynx^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 (VIN = 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.
