Description
The 12A Digital Pico DLynxTM power modules are non-isolated dc-dc converters that can deliver up to 12A 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 0.45Vdc 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 overtemperature protection. The PMBus interface supports a range of commands to both control and monitor
the module. The module also includes the Tunable LoopTM 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.
