Boost Regulator with Integrated Schottky and Input Disconnect SwitchThe ISL97701 represents a high efficiency boost converterwith integrated boost FET, boost diode and input disconnectFET.With an input voltage of 2.3V to 5.5V the ISL97701 has anoutput capability of up to 50mA at 18V using integrated500mA switches. Efficiencies are up to 87%. Theintegrated protection FET is used to disconnect the boostinductor from the input supply whenever an output faultcondition is detected, or when the device is disabled. Thisgives 0 output current in the disabled mode, compared tostandard boost converters where current can still flow whenthe device is disabled.The ISL97701 comes in the 10 Ld 3x3 DFN package and isspecified for operation over the -40°C to +85°C temperature range.
