TPS2231PWPR datasheet by Texas Instruments

TPS2231PWPR Frequently Asked Questions (FAQs)

• What is the maximum current rating for the TPS2231PWPR?
  The maximum current rating for the TPS2231PWPR is 3A, but it's recommended to derate the current to 2.5A for reliable operation.
• How do I calculate the output voltage of the TPS2231PWPR?
  The output voltage of the TPS2231PWPR can be calculated using the formula: Vout = (R1 / R2) * (Vin - Vref), where R1 and R2 are the resistors in the feedback network, Vin is the input voltage, and Vref is the reference voltage (typically 1.25V).
• What is the purpose of the EN (enable) pin on the TPS2231PWPR?
  The EN (enable) pin is used to turn the regulator on or off. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled. This pin can be used to implement power sequencing or to reduce power consumption in standby modes.
• How do I ensure stability and prevent oscillations in the TPS2231PWPR?
  To ensure stability and prevent oscillations, it's essential to follow the recommended layout guidelines, use a sufficient output capacitor (at least 10uF), and ensure that the input capacitor is properly sized and placed close to the regulator. Additionally, the feedback network should be designed to provide a stable gain margin.
• What is the thermal shutdown temperature for the TPS2231PWPR?
  The thermal shutdown temperature for the TPS2231PWPR is typically around 150°C to 160°C. When the junction temperature exceeds this threshold, the regulator will shut down to prevent damage.
