The switching frequency runs between 1.25 MHz and 1.5 MHz, which keeps the inductor and output capacitor physically small — typically a 2.2 µH to 4.7 µH inductor and a 10 µF ceramic output cap.
Determines if the part provides the exact regulated voltage required for the design.
Critical for long-term availability and production planning.
Directly enables purchase and fulfillment of BOM requirements.
Essential for PCB layout and ensuring correct connectivity.
Ensures the part can safely handle the supply voltage range in the application.
Needed if the original part is unavailable or to compare alternatives for cost/performance.
