7.3 Application Curves

Figure 7-2 shows the typical response of the AMC23C11 to a triangular input waveform with an amplitude of 310mVPP. The output (OUT) switches when VIN crosses the 250mV level determined by the REF pin voltage that is biased to 250mV in this example.

The integrated LDO of the AMC23C11 greatly relaxes the power-supply requirements on the high-voltage side and allows powering the device from non-regulated transformer, charge pump, and bootstrap supplies. As given by the following image, the internal LDO provides a stable operating voltage to the internal circuitry, allowing the trip thresholds to remain mostly undisturbed even at ripple voltages of 2VPP and higher.
