Description
The 3A Digital PicoDLynx TM power modules are non-isolated dc-dc converters that can deliver up to 3A 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
0.45Vdc 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.
