Pinout
1. SW (Switch Pin): This is the switch pin, where the inductor is connected. It handles the switching action for the boost operation.
2. GND (Ground Pin): This is the ground reference for the circuit.
3. FB (Feedback Pin): This pin is used to receive the feedback voltage. It monitors the output voltage to regulate it by comparing it against an internal reference.
4. SHDN (Shutdown Pin): This pin is used to enable or disable the IC. Pulling it low typically shuts down the device to save power.
5. VIN (Input Voltage Pin): This pin takes the input voltage for the IC, which is then boosted to a higher level on the output.
The LT1613 is primarily used in applications requiring a compact and efficient boost converter solution.
