DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the package type matches the QFN-24 footprint required for the design. Ensure the operating temperature grade aligns with the intended environmental conditions. Cross-reference the manufacturer part number directly with official Analog Devices documentation to avoid counterfeit components.

DC DC Switching Controllers Selection Notes

Select this component when a single-output synchronous buck controller with wide input voltage capability is required. The differential remote sensing feature makes it suitable for applications demanding tight load regulation over long PCB traces. Consider the 200kHz to 1.2MHz frequency range for optimizing efficiency versus component size. Verify that the external MOSFET selection supports the maximum current requirements of the target application.
