Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'VY+T' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the FLB variant matches the intended thermal and electrical specifications for the target application environment. Ensure compliance with RoHS directives as indicated by the plus sign in the part number. Cross-reference the manufacturer's latest documentation to validate current production status and availability constraints.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 2.5A output current is sufficient for the load requirements within a 36V maximum input constraint. The 2.1MHz switching frequency offers a balance between size and efficiency compared to lower frequency alternatives. Consider the 15-pin FC2QFN package dimensions if board space is limited. Verify that the external inductor and capacitor values align with the internal compensation network for stable operation at the desired output voltage.
