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.
