Description
The 2 × 12A Digital Dual MicroDlynx TM power modules are non-isolated dc-dc converters that can deliver up to 2 × 12A of output
current. These modules operate over a wide range of input voltage (V
IN
= 4.5Vdc-14.4Vdc) and provide precisely regulated output
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
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.
