DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'MHX' indicates tape-and-reel packaging when ordering. Confirm AEC-Q100 qualification requirements match your application's automotive grade needs. Ensure the 16-HTSSOP footprint aligns with your PCB layout constraints. Check for RoHS3 compliance if environmental regulations apply. Validate that the non-synchronous topology suits your efficiency targets compared to synchronous alternatives.

DC DC Switching Controllers Selection Notes

Select this controller for applications requiring a wide input voltage range up to 42V without internal power switches. Consider the non-synchronous design for cost-sensitive or high-voltage scenarios where external MOSFETs are preferred. Evaluate the 50kHz to 1MHz frequency range against EMI and inductor size requirements. Verify that the 2A output current capability meets the load demands. Ensure compatibility with external N-channel MOSFETs for optimal performance.
