7 Ipk Sense Peak Current Sense Input to monitor the voltage drop across an external resistor to limit the peakcurrent through the circuit
8 N.C. Pin Not Connected
ExposedPad
Exposed Pad The exposed pad beneath the package must be connected to GND (Pin 4). Additionally, usingproper layout techniques, the exposed pad can greatly enhance the power dissipation capabilitiesof the NCP3063.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above theRecommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affectdevice reliability.1. This device series contains ESD protection and exceeds the following tests:
Pin 1−8: Human Body Model 2000 V per AEC Q100−002; 003 or JESD22/A114; A115Machine Model Method 200 V
2. This device contains latch−up protection and exceeds 100 mA per JEDEC Standard JESD78.3. The relation between junction temperature, ambient temperature and Total Power dissipated in IC is TJ = TA + R� PD4. The pins which are not defined may not be loaded by external signals
6. The VIPK(Sense) Current Limit Sense Voltage is specified at static conditions. In dynamic operation the sensed current turn−off value dependson 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.
