Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'CER' against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure compatibility with your PCB footprint, as the USP-C-EP-6 package requires precise thermal and electrical pad design. Cross-reference the RoHS status directly with the latest documentation provided by Torex Semiconductor before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.3V output is required from a 2.5V to 5.5V input source. The 1.5A current capability suits moderate load applications. Consider the 3MHz switching frequency for smaller external inductor and capacitor sizes compared to lower-frequency alternatives. Verify that the operating temperature range meets the environmental requirements of the target application.
