ADP1073–SPECIFICATIONS
This specification guarantees that both the high and low trip point of the comparator fall within the 200 mV to 222 mV range.
This specification guarantees that the output voltage of the fixed versions will always fall within the specified range. The waveform at the sense pin will exhibit a
100 k resistor connected between a 5 V source and the AO pin.
The ADP1073 is guaranteed to withstand continuous application of +1.6 V applied to the GND and SW2 pins while V
sawtooth shape due to the comparator hysteresis.
