Description

The 12A Digital Pico DLynx

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 Loop

response of the converter to match the load with reduced amount of output capacitance leading to savings on cost

and PWB area.
