Pinout
The TPS62290DRVR comes in a 6-pin WSON package. Here is a brief description of its pin functions:
1. VIN: The input voltage supply pin where the input voltage is connected.
2. GND: The ground pin, which is connected to the ground plane of the circuit.
3. SW: The switch pin, connected to the inductor for energy transfer.
4. FB: The feedback pin, used to set the output voltage via an external resistor divider network.
5. EN: The enable pin, which turns the device on or off.
6. NC: No connection, this pin is not internally connected and can be left floating.
This configuration allows for efficient power conversion in a compact space, making it suitable for portable devices and other electronic applications requiring voltage regulation.
