I am currently working on the power stage section of the project. I need to select a step-down (buck) controller IC that can efficiently convert an input voltage range of 9–24 V down to approximately 9 V at the output. I am considering TPS5430DDA.
Buck Controller Recommendation: Is TPS5430DDA Suitable for 9–24 Vin → 9 Vout?
