The maximum input voltage that can be applied to the TPS2817DBVT is 18V, but it's recommended to keep it below 15V for reliable operation.
To ensure stability, make sure to follow the recommended layout and component selection guidelines in the datasheet, including the use of a 10uF ceramic capacitor at the input and a 1uF ceramic capacitor at the output.
The minimum ESR required for the output capacitor is 0.1 ohms, but it's recommended to use a capacitor with an ESR of 0.05 ohms or less for optimal performance.
The TPS2817DBVT is rated for operation up to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C. Make sure to follow the thermal design guidelines in the datasheet to ensure reliable operation.
The output voltage ripple can be calculated using the formula: ΔVout = (Iout * ESL) / (Cout * fsw), where ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency.
