NOTES:

A. Total current consumption is the sum of I

switching) and the sum of I

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 6.1 V.

C. BYPASS pin is not intended for sourcing supply current to external circuitry.

D. See Typical Performance Characteristics section for BYPASS pin start-up charging waveform.

E. For current limit at other di/dt values, refer to Figure 25.

F. This parameter is derived from characterization.

G. This parameter is derived from the change in current limit measured at 1X and 4X of the di/dt shown in the I

LIMIT

specification.

H. Breakdown voltage may be checked against minimum BV

to but not exceeding minimum BV

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

frequency).
