Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'B17' confirms the 1.7V fixed output voltage, as this variant differs from other XC9285 models with different voltage codes. Confirm the 'G' suffix indicates RoHS compliance and halogen-free status per manufacturer specifications. Ensure the USP-C-EP-6 package footprint matches your PCB design requirements before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.7V output is required from a 2.5V to 5.5V input source. It is suitable for designs prioritizing small solution size due to the integrated capacitor-less stability. Consider the 1.2MHz switching frequency for balancing component size and efficiency. Verify that the 1A continuous current rating meets the load requirements of the target application circuit.
