Data Sheet

FN6474.1
Boost Regulator with Integrated Schottky
and Input Disconnect Switch
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擄C to +85擄C temperature
range.
