NOTES:

A. For specifications with negative values, a negative temperature coefficient corresponds to an increase in magnitude with increasing

temperature, and a positive temperature coefficient corresponds to a decrease in magnitude with increasing temperature.

B. For externally adjusted current limit values, please refer to Figure 35 (Current Limit vs. External Current Limit Resistance) in the

Typical Performance Characteristics section.

C. Breakdown voltage may be checked against minimum BVDSS specification by ramping the DRAIN pin voltage up to but not

exceeding minimum BVDSS.

D. It is possible to start up and operate DPA-Switch at DRAIN voltages well below 16 V. However, the CONTROL pin charging

current is reduced, which affects start-up time, auto-restart frequency, and auto-restart duty cycle. Refer to Figure 45, the

characteristic graph on CONTROL pin charge current (IC) vs. DRAIN voltage for low voltage operation characteristics.
