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 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 startup 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. Breakdown voltage may be checked against minimum BVDSS specification by ramping the DRAIN pin voltage up

to but not exceeding minimum BVDSS.

I. Auto-restart on time has the same temperature characteristics as the oscillator (inversely proportional to

frequency).
