TPS2231MRGPR-1 datasheet by Texas Instruments

TPS2231MRGPR-1 Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the TPS2231MRGPR-1?
  The maximum operating temperature range for the TPS2231MRGPR-1 is -40°C to 85°C.
• How do I ensure the TPS2231MRGPR-1 is properly powered up and initialized?
  To ensure proper power-up and initialization, make sure to follow the recommended power-up sequence, which is to apply VCC first, followed by EN (enable) and then VIN (input voltage). Also, ensure that the input voltage is within the recommended range and that the output capacitor is properly sized.
• What is the recommended input capacitor value and type for the TPS2231MRGPR-1?
  The recommended input capacitor value is 10uF to 22uF, and it should be a low-ESR ceramic capacitor, such as X5R or X7R, to ensure stable operation and minimize noise.
• How do I calculate the output voltage of the TPS2231MRGPR-1?
  The output voltage of the TPS2231MRGPR-1 can be calculated using the formula: VOUT = 0.8 x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB (feedback) pin. The output voltage range is 0.8V to 5.5V.
• What is the maximum output current capability of the TPS2231MRGPR-1?
  The maximum output current capability of the TPS2231MRGPR-1 is 3A, but it can be limited by the thermal performance of the package and the PCB design. It's recommended to check the thermal performance and adjust the output current accordingly.
