Application Curves

Figure 8-2 shows the typical response of the AMC22C11-Q1 to a triangular input waveform with an amplitude of 310 mVPP. The output (OUT) switches when VIN crosses the 250-mV level determined by the REF pin voltage that is biased to 250 mV in this example.

Figure 8-2 Output Response of the AMC22C11-Q1 to a Triangular Input Waveform

The integrated LDO of the AMC22C11-Q1 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 2 VPP and higher.
