Connecting a PC to DC2728A
You can use a PC to reconfigure the power management
features of the LTC7880 such as: nominal V
OUT
, mar-
gin set points, OV/UV limits, temperature fault limits,
sequencing parameters, the fault log, fault responses,
GPIOs and other functionalities. The DC1613A dongle
may be plugged when V
IN
is present.
