Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation as UMW Youtai Semiconductor to ensure authenticity. Confirm the specific package type matches the required PCB footprint, noting the TO-263-6 or D2PAK form factor. Check RoHS3 compliance status if environmental regulations apply to the final assembly. Ensure the fixed 12V output variant is selected rather than the adjustable version.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output is required from an input source exceeding 12V but below 57V. The 2A current rating suits moderate load applications without requiring external pass transistors. The 150kHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the thermal performance of the TO-263 package for heat dissipation requirements in the target enclosure.
