TPS2045AD Frequently Asked Questions (FAQ)

  • The TPS2045AD can handle input voltages up to 40V, but it's recommended to keep it below 30V for optimal performance and reliability.

  • 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.

  • The TPS2045AD can operate with input voltages as low as 2.7V, but the output voltage regulation may not be guaranteed below 3.5V.

  • The TPS2045AD 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.

  • The output voltage (VOUT) can be calculated using the formula: VOUT = 1.24V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin.
