USB To STAR Convertar

The USB To STAR Convertar  . The output voltage can be set externally using a
resistor divider to any value between 0.8 V and the input supply minus the resistive drops on the converter path.
Each converter features enable pin that allows a delayed start-up for sequencing purposes, soft start pin that
allows adjustable soft-start time by choosing the soft-start capacitor, and a current limit (RLIM) pin that enables
designer to adjust current limit by selecting an external resistor and optimize the choice of inductor. All converters
operate in ‘hiccup mode’: Once an over-current lasting more than 10 ms is sensed in any of the converters, they
will shut down for 10 ms and then the start-up sequencing will be tried again. If the overload has been removed,
the converter will ramp up and operate normally.
