NOTES:
A. Total current consumption is the sum of I S1 and I DSS when FEEDBACK pin voltage is ≥2 V (MOSFET not
switching) and the sum of I S2 and I DSS when FEEDBACK pin is shorted to SOURCE (MOSFET switching).
B Since the output MOSFET is switching, it is dif?cult to isolate the switching current from the supply current at the
DRAIN. An alternative is to measure the BYPASS pin current at 6 V.
C. See Typical Performance Characteristics section Figure 14 for BYPASS pin start-up charging waveform.
D. This current is only intended to supply an optional optocoupler connected between the BYPASS and FEEDBACK
pins and not any other external circuitry.
E. For current limit at other di/dt values, refer to Figure 13.
F. This parameter is guaranteed by design.
G. This parameter is derived from characterization.
H. Auto-restart on time has the same temperature characteristics as the oscillator (inversely proportional to
frequency).
