Description
The ISL97701 represents a high efficiency boost converter with integrated boost FET, boost diode and input disconnect FET.
With an input voltage of 2.3V to 5.5V the ISL97701 has an output capability of up to 50mA at 18V using integrated 500mA switches. Efficiencies are up to 87%. The integrated protection FET is used to disconnect the boost inductor from the input supply whenever an output fault condition is detected, or when the device is disabled. This gives 0 output current in the disabled mode, compared to standard boost converters where current can still flow when the device is disabled.
The ISL97701 comes in the 10 Ld 3x3 DFN package and is specified for operation over the -40°C to +85°C temperature range.
The price listed is the manufacturer's suggested retail price for quantities of 1K units. However, prices in today's market are fluid and may change without notice.
