Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix KCER against the manufacturer's official datasheet to confirm pinout, tolerance, and tape-and-reel specifications. Ensure compatibility with your PCB footprint and thermal requirements. Cross-reference the part number with authorized distributors to confirm authenticity and availability status before finalizing procurement decisions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.75 V output is required from a 2.5 V to 5.5 V input source. The 1.5 A current capability suits moderate load applications. Consider the 1.2 MHz switching frequency for balancing component size and efficiency. Verify that the USP-C-EP-6 package fits the design constraints and that the -40°C to +105°C range meets environmental needs.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9287 series of synchronous buck converters. It shares the HiSAT-COT architecture with other variants in the family but differs in output voltage and control mode. The XC9287 series is designed for portable equipment, offering high efficiency and low standby current compared to linear regulators.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes within the same series include XC9287A1ACER-G (1.05 V output) and XC9287A2KCER-G (2.75 V output). These share identical packaging and control modes but provide different fixed output voltages. Verify that the alternative voltage matches the load requirements.
