Pinout

The LT3462AES6 is a high-efficiency step-up DC/DC converter by Analog Devices. It is housed in a 6-lead SOT-23 package. Here’s a concise overview of the pin functions:
1. SW (Pin 1): This is the switch pin where the inductor is connected. It handles high current and should be minimized in trace length to reduce EMI.
2. GND (Pin 2): This is the ground pin and serves as the reference point for all the other pins.
3. FB (Pin 3): This is the feedback pin. It receives the output voltage through a resistor divider to regulate the output.
4. SHDN (Pin 4): This is the shutdown pin. Pulling this pin low puts the device into shutdown mode, reducing the supply current to a minimal value.
5. VIN (Pin 5): This is the input voltage pin, which powers the internal circuitry of the IC.
6. NC (Pin 6): This pin is not connected internally and typically left floating or connected to ground.
This concise pin description should suffice in providing a quick understanding of the LT3462AES6's functionality.
