5. NCP3063: Tlow = 0°C, Thigh = +70°C;

NCP3063B, NCV3063: Tlow = −40°C, Thigh = +125°C

6. The

VIPK(Sense) Current Limit Sense Voltage is specified at static conditions. In dynamic operation the sensed current turn−off value depends

on comparator response time and di/dt current slope. See the Operating Description section for details.

7. Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient temperature as possible.

8. NCV prefix is for automotive and other applications requiring site and change control.
