Pinout
The TPS563203DRLR is a step-down (buck) converter from Texas Instruments. It is provided in an 8-pin package. Here's a brief overview of its pin functions:
1. VIN: (Pin 1) Input voltage supply. Connect this pin to the input supply voltage.
2. EN: (Pin 2) Enable pin. Used to enable or disable the device. A high level turns the device on, while a low level turns it off.
3. FB: (Pin 3) Feedback pin. Connect this to the midpoint of the resistor divider to set the output voltage.
4. GND: (Pin 4) Ground pin. Connect this pin to the system ground.
5. SW: (Pin 5) Switch node. Connect to the inductor and catch diode.
6. BOOT: (Pin 6) Bootstrap capacitor connection. Connect an external capacitor between this pin and the SW pin to supply the high-side gate driver.
7. NC: (Pin 7) No connection. Internally not connected; can be left floating.
8. VREG5: (Pin 8) 5V internal regulator output. This is generally used for internal purposes.
These pins support the primary function of the TPS563203DRLR, which is efficient step-down voltage conversion with a fixed 3.3V output.
