Pinout
Here's a brief overview of the pin functions:
1. Pin 1 (SW): This is the switch pin where the inductor is connected. It is responsible for switching current to produce a boosted output voltage.
2. Pin 2 (GND): The ground pin, which is the reference point for the circuit and is connected to the negative terminal of the power supply.
3. Pin 3 (FB): The feedback pin. It is used to set the output voltage by comparing the voltage at this pin to an internal reference voltage.
4. Pin 4 (EN): The enable pin. It is used to turn the boost converter on or off. A high voltage level enables the device, while a low voltage level disables it.
5. Pin 5 (VIN): This is the input voltage pin where the power source is connected.
The MCP1662 is designed for applications requiring efficient step-up voltage conversion, providing output voltages higher than the input power supply voltage.
