Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific part number matches the required fixed 12V output configuration, as the LM2675 series includes adjustable and other fixed voltage variants. Confirm the through-hole MDIP package requirement aligns with the PCB footprint design. Ensure compliance with RoHS standards indicated by the NOPB suffix before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output is required from an 8V to 40V input source with up to 1A current capability. The 260kHz switching frequency allows for smaller inductors and capacitors compared to lower-frequency alternatives. Consider the through-hole MDIP package if board space permits and manual assembly or specific mounting constraints are present.
