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 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. Features • 100+ Volt Input Capability • Adjustable Output from 1.5V to 20V • Up to 100mA Output Current • Overcurrent Protection • Over-Temperature Protection • ENABLE and ENABLE_N Inputs • Package Compliant with IPC2221A, Creepage and Clearance Spacing Requirements • Pb-Free (RoHS Compliant) Applications • Telecom/Datacom DC/DC Converters • Low Power Bias Supplies Ordering Information PART NUMBER (Note) PART MARKING TEMP.
