APPLICATIONS INFORMATION - SWITCHED CAPACITOR BOOST CIRCUIT
these cases, the application can use V_out as an
interrupt source in addition to power source, with a
rising or falling edge triggering the desired action.

frequency. Usable bandwidth refers to the frequency range
over which the setup produced voltages exceeding the
circuit’s turn-on threshold (2.4V), producing output pulses.
