Pinout
The TPS62203DBVR is a step-down converter (buck converter) from Texas Instruments. It is typically used in applications requiring efficient power conversion with low output voltages. The device is housed in a 5-pin SOT-23 package. The pin functions are as follows:
1. Pin 1 (SW): Switch pin. This is the connection for the inductor.
2. Pin 2 (GND): Ground pin. This pin should be connected to the ground plane or ground traces.
3. Pin 3 (FB): Feedback pin. This is used to set the output voltage via an external resistor divider network.
4. Pin 4 (EN): Enable pin. This pin is used to enable or disable the device. Pulling it high enables the converter, while pulling it low puts the device into shutdown mode.
5. Pin 5 (VIN): Input voltage pin. This is where the input supply voltage is applied.
