Description
The 20A Digital Micro DLynx
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 #
TM #
protocol, remote On/Off, adjustable output
control. Features include a digital interface using the PMBus
TM #
interface supports a range of commands to
voltage, over current and over temperature protection. The PMBus
TM
both control and monitor the module. The module also includes 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.
