Description
TM
The 2 6A Digital Dual MicroDlynx power modules are non-isolated dc-dc converters that can deliver up to 2 6A of output
current. These modules operate over a wide range of input voltage (V = 4.5Vdc-14.4Vdc) and provide precisely regulated output
IN
voltages from 0.51Vdc to 5.5Vdc, programmable via an external resistor and PMBus control. Features include a digital interface
using the PMBus 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
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.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress
ratings only, functional operation of the device is not implied at these or any other conditions in excess of those given in the
operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect the
device reliability.
