Pinout
1. Pin Count: The LT1617ES5 has a total of 5 pins.
2. Pin Functions:
- Pin 1 (SW): This is the switch pin. It connects to the inductor and the diode in the boost converter circuit.
- Pin 2 (GND): The ground pin, which serves as the return path for the circuit.
- Pin 3 (FB): The feedback pin, which is used to set the output voltage by connecting it to a resistor divider network.
- Pin 4 (SHDN): The shutdown pin, which can be used to enable or disable the device. Pulling it low shuts down the converter, reducing the quiescent current.
- Pin 5 (VIN): This is the input voltage pin, where the supply voltage is connected.
The LT1617ES5 provides efficient power conversion suitable for low-power applications, with the ability to operate from input voltages as low as 1V.
