ISL6719

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. The features of ISL6719 are as follows: (1)100+ Volt Input Capability; (2)Adjustable Output from 1.5V to 20V; (3)Up to 100mA Output Current; (4)Overcurrent Protection; (5)Over-Temperature Protection; (6)ENABLE and ENABLE_N Inputs.

The following is about the absolute maximum ratings of ISL6719: (1)Supply Voltage, VPWR: GND - 0.3V to +105V; (2)AUXIN, VSW_FB: GND - 0.3V to +40V; (3)COMPB: GND - 0.3V to +30V; (4)VSW: GND - 0.3V to +25V; (5)All Others: GND - 0.3V to +6.0V.

The electrical characteristics of the ISL6719 are: (1)Supply Voltage: 100 V; (2)Start-Up Current (IVPWR): 250 A typ and 450 A max at VPWR = 12V ; (3)Operating Current (IVPWR): 1.1mA typ and 2.0mA max at VSW Enabled, VPWR = 100V, VSW = 10V, 20V, IVPWR - IVSW, 1.1 mA typ and 2.0 mA max at VSW Disabled, VPWR = 100V; (4)UVLO START Threshold: 13.0V min and 16.5V max at VSW Disabled; (5)UVLO STOP Threshold: 12.0 V min and 15.0 V max at VSW Disabled ; (6)Hysteresis: 0.8 V min, 1.2 V typ and 1.7 V max at UVLO START - UVLO STOP.
