ISL6719
100V Linear Bias Supply
The ISL6719 is a low cost linear regulator for generating a low
voltage bias supply from intermediate distributed
voltages commonly used in telecom and datacom applications.
It provides a single adjustable output rated at 100mA from either the input source or an auxiliary source such as a transformer winding.
The auxiliary source is selected whenever it has sufficient
voltage to sustain the output.
The ISL6719 may be used as a start-up or a continuous low power regulator.
When operating as a start-up regulator, it is capable of sourcing 100mA from a 100V source for short durations.
This period of time allows the power supply to start-up and provide ...
