ELECTRICAL CHARACTERISTICS (continued)
(V+ = V L = 5V or V+ = 5.5V to 23V, V EN = 5V, T A = T J = -40°C to +125°C, unless otherwise noted. Circuits of Figures 5 and 6. Typical
values are at T A = T J = +25°C.) (Note 2)

Note 2: 100% tested at T A = +25°C and T A = +125°C. Limits from T A = -40°C to +25°C are guaranteed by design.
Note 3: Output current may be limited by the power dissipation of the package. See the Power Dissipation section in the Applications
Information section.
Note 4: From the rising edge of the SOURCE waveform to the rising edge of the CKO waveform.
Note 5: SYNC input frequency is equal to the switching frequency.
Note 6: From the SYNC rising edge to SOURCE rising edge.
Note 7: RESET goes high 200ms after V OUT crosses this threshold, PGOOD goes high after V OUT crosses this threshold.
