Frequently Asked Questions
What is the input voltage range of the LM25117PMHX/NOPB?
The LM25117PMHX/NOPB operates over a wide input voltage range of 4.5V to 42V, making it suitable for industrial 12V/24V bus rails and automotive applications where the input can vary significantly.
What package does the LM25117PMHX/NOPB come in?
It uses TI HotRod WSON-10 package (3mm x 3mm, 10-pin), a leadless low-inductance package designed for high-frequency power conversion. The /NOPB suffix confirms the part is lead-free and RoHS compliant.
What is the maximum output current of the LM25117PMHX/NOPB?
The LM25117PMHX/NOPB supports up to 6A continuous output current with cycle-by-cycle peak current limiting for overcurrent protection, depending on external FET and inductor selection.
What are suitable replacement or alternative parts for the LM25117PMHX/NOPB?
Compatible alternatives include the LM25117QMH (automotive AEC-Q100 version), LM5116 (higher 75V input variant), and TPS40170 (similar wide-Vin synchronous buck controller from TI). Verify pinout and compensation network before swapping.
Is the LM25117PMHX/NOPB suitable for automotive designs?
The standard LM25117PMHX/NOPB is rated for -40C to 125C and 4.5V-42V, covering many automotive conditions. For full AEC-Q100 qualification, consider the LM25117QMH automotive-grade variant.
