TPS2049DR datasheet by Texas Instruments

TPS2049DR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the TPS2049DR can handle?
  The TPS2049DR can handle input voltages up to 40V, but it's recommended to keep it below 30V for optimal performance and reliability.
• How do I ensure the TPS2049DR is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a low-ESR output capacitor, and add a 10nF-100nF ceramic capacitor between the VIN and GND pins.
• What is the minimum input voltage required for the TPS2049DR to operate?
  The TPS2049DR can operate with input voltages as low as 2.7V, but the output voltage regulation may not be guaranteed below 3.5V.
• Can I use the TPS2049DR in a high-temperature environment?
  The TPS2049DR is rated for operation up to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C. Ensure proper thermal design and heat sinking to prevent overheating.
• How do I calculate the output voltage of the TPS2049DR?
  The output voltage (VOUT) 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 internal reference voltage (1.25V).
