Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'CMR-G' against the official Torex datasheet to confirm package type and tape/reel specifications. Ensure compatibility with the required 2.2 V fixed output and 800 mA current rating for your design. Cross-reference RoHS compliance status directly with manufacturer documentation prior to integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.2 V output is required from inputs as low as 0.65 V. The 1.2 MHz switching frequency allows for smaller external inductors compared to lower-frequency alternatives. Consider the 800 mA peak capability for transient loads, while ensuring thermal management aligns with the SOT-25-5 package constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9142 series of 0.8 A synchronous step-up DC/DC converters. The series is characterized by low quiescent current and integrated load switches. The XC9142F variant specifically denotes the 1.2 MHz switching frequency option within the family, distinguishing it from higher-frequency models like the XC9142D or XC9142C series.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes within the same series include XC9142F22DMR-G (WLP package) or XC9142F22DER-G (DFN package), provided pinout compatibility is verified. For different output voltages, check XC9142FxxCMR-G variants where xx corresponds to the desired voltage code.
