The TPS62821DLCR is a step-down (buck) converter from Texas Instruments. It typically comes in a 6-pin package. Here is a brief overview of the pin functions:
1. VIN: This is the input voltage pin where the supply voltage is connected. It accepts a wide range of input voltages.
2. SW: Connected to the inductor, this pin is the switch node that alternates between VIN and ground.
3. GND: This pin is the ground reference for the device and must be connected to the system ground.
4. FB: The feedback pin is used for voltage regulation. Connect it to the output voltage via a resistor divider to set the desired output voltage.
5. EN: The enable pin is used to turn the device on or off. Pulling it high enables the converter, while pulling it low disables it.
6. PG: The power-good pin indicates the status of the output voltage. It is an open-drain output that goes high when the output voltage is within a certain range.
