NCP3063 Pinout Overview (SOIC-8 Package):
Pin # Pin Name Pin Function 1 VCC Input voltage to the IC (3.5V to 40V) for the power supply to the converter. 2 EN Enable pin. A logic high (>= 2V) enables the IC; a logic low disables it. 3 GND Ground pin for the IC. 4 SW Switch pin for the internal MOSFET to drive the inductor and load. 5 VOUT Output voltage from the regulator; this pin is connected to the load. 6 FB Feedback pin for controlling the output voltage, typically connected to a voltage divider. 7 ISENSE Current sense pin to monitor output current for feedback regulation. 8 NC No connection (often used for internal purposes in the IC).Pin Function Descriptions (Detailed):
Pin 1 - VCC (Input Voltage): The VCC pin is used to supply the power to the internal circuitry of the IC. The NCP3063 operates within a voltage range of 3.5V to 40V. Ensure that this voltage is within the acceptable range, as a higher input voltage could damage the IC. Pin 2 - EN (Enable Pin): The EN pin is used to enable or disable the IC. To enable the device, apply a voltage greater than or equal to 2V. To disable, drive this pin low (0V). This pin helps in turning the regulator on or off to conserve power when needed. Pin 3 - GND (Ground): This pin should be connected to the ground of the system circuit. Proper grounding ensures stable operation and reduces noise in the output. Pin 4 - SW (Switch Pin): The SW pin is the switching node that connects to the external inductor. It is used to control the current flow through the inductor during the switching cycle. This pin should not be left floating. Pin 5 - VOUT (Output Voltage): The VOUT pin provides the output voltage regulated by the NCP3063. The voltage at this pin is determined by the feedback loop and can be adjusted using external resistors in the voltage divider configuration. Pin 6 - FB (Feedback Pin): The FB pin is used to control the output voltage regulation by comparing the voltage at this pin with the reference voltage. Typically, a resistor divider network is used to set the desired output voltage. Pin 7 - ISENSE (Current Sense Pin): This pin is used to monitor the output current, allowing the IC to regulate based on load conditions. It can be used in applications requiring current sensing for protection or accurate regulation. Pin 8 - NC (No Connection): This pin is not internally connected and is not used in the external circuit. It’s typically used for manufacturing or testing purposes.Frequently Asked Questions (FAQ) - NCP3063
