Procurement Notes

Verify the specific suffix '10' against the manufacturer's official datasheet to confirm pinout and electrical specifications match your design requirements. Ensure compatibility with the required input voltage range and thermal management solutions for the QFN package. Cross-reference ordering information directly with Alpha & Omega Semiconductor authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a compact, synchronous buck regulator is needed for inputs up to 28V. The 4A output capacity suits moderate load applications. Consider the 1MHz frequency for smaller inductor sizes compared to lower-frequency alternatives. Verify that the adjustable output range meets the target voltage requirements of the specific circuit design.
