Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix 'T' indicates tape-and-reel packaging configuration as specified by the manufacturer. Confirm that the part number matches the specific 12-lead DFN footprint requirements for your PCB layout. Ensure compatibility with the 500 kHz switching frequency constraints in your system design before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 5A output current is required with a wide input voltage range up to 18V. The integrated FETs reduce external component count compared to controller-only solutions. Consider the 12-lead DFN package size for space-constrained designs. Verify thermal performance requirements given the high current capability in a small footprint.
