ISL6719
ISL6719 is 100V Linear Bias Supply manufactured by Renesas.
100V Linear Bias Supply
The ISL6719 is a low cost linear regulator for generating a low voltage bias supply from intermediate distributed voltages monly used in tele and data applications. It provides a single adjustable output rated at 100m A 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 100m A from a 100V source for short durations. This period of time allows the power supply to start-up and provide an alternate power source, such as the output of a transformer winding, to the AUXIN input. This allows the regulated output to operate from a lower source voltage to minimize power loss.
