NOTES:
A. Total current consumption is the sum of IS1 and IDSS when FEEDBACK pin voltage is ≥2 V (MOSFET not switching) and the sum of
IS2 and IDSS when FEEDBACK pin is shorted to SOURCE (MOSFET switching).
B
Since the output power MOSFET is switching, it is difficult 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 15 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 14.
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).
