NOTES
1This specification guarantees that both the high and low trip point of the comparator fall within the 210 mV to 230 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 saw-
tooth shape due to the comparator hysteresis.
3100 kresistor connected between a 5 V source and the AO pin.
4The ADP1110 is guaranteed to withstand continuous application of +1.6 V applied to the GND and SW2 pins while V IN, ILIM, and SW1 pins are grounded.
5All limits at temperature extremes are guaranteed via correlation using standard statistical quality control methods.
Specifications subject to change without notice.
