NOTES
*Denotes the specifications that apply over the full operating temperature range.
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 k
resistor connected between a 5 V source and the A0 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.
Specifications subject to change without notice.
