NOTES
1This specification guarantees that both the high and low trip point of the comparator fall within the 200 mV to 222 mV range.
2This 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
sawtooth shape due to the comparator hysteresis.
3100 kΩ resistor connected between a 5 V source and the AO pin.
4The ADP1073 is guaranteed to withstand continuous application of +1.6 V applied to the GND and SW2 pins while VIN, ILIM and SW1 pins are grounded.
All limits at temperature extremes are guaranteed via correlation using standard Quality Control methods.
Specifications subject to change without notice.
