Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'CFDDAR' or 'CFDDA' matches the required tape-and-reel or cut-tape packaging format. Confirm the operating temperature grade corresponds to industrial requirements. Ensure the 8-SO-PowerPad footprint aligns with the PCB layout design. Cross-reference the manufacturer part number against official Texas Instruments documentation to avoid counterfeit components.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a wide input voltage range up to 36V is required alongside moderate current delivery. The fixed 2.1MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the thermal performance of the PowerPAD package for heat dissipation needs. Verify that the adjustable output range meets the specific load voltage requirements of the target application circuit.
