A good PCB layout for the TPS22992SRXNR involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the traces between the device and the capacitors. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
To ensure stability, make sure to follow the recommended PCB layout, use the recommended input and output capacitors, and ensure that the input voltage is within the recommended range. Additionally, it's recommended to add a small ceramic capacitor (e.g. 10nF) between the VIN and GND pins to filter out high-frequency noise.
The TPS22992SRXNR can deliver up to 2A of continuous current, but it's recommended to derate the current based on the ambient temperature and the PCB layout. It's also important to ensure that the input voltage is sufficient to support the desired output current.
The output voltage of the TPS22992SRXNR can be adjusted by using a resistive divider network between the VOUT and GND pins. The recommended resistors are 1% tolerance, and the ratio of the resistors determines the output voltage. For example, a 1kΩ and 2kΩ resistor divider would set the output voltage to 1.8V.
The EN (enable) pin is used to turn the device on and off. When the EN pin is high, the device is enabled and the output voltage is regulated. When the EN pin is low, the device is disabled and the output voltage is disconnected from the input voltage.
