ISL97702
Data Sheet
Boost with Dual Reference Outputs
The ISL97702 represents a high efficiency, boost converter
with integrated boost FET, boost diode and input disconnect
FET. A dual feedback circuit allows simple switching
between two pre-defined output voltages using a single logic
input.
With an input voltage of 2.3V to 5.5V the ISL97702 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.
