Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'CMR' against the official Torex datasheet to confirm package type and tape/reel specifications. Ensure the operating environment remains within the stated thermal limits. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and avoid counterfeit components during sourcing.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.9 V output is required from a single-cell lithium battery or similar low-voltage source. The 800 mA current capability suits moderate load applications. Consider the 1.2 MHz frequency for balancing component size and efficiency needs in compact designs.

Voltage Regulators - DC DC Switching Regulators Part Context

This model belongs to the XC9141 series of 0.8 A step-up DC/DC converters. It shares architectural similarities with variants like XC9141B33CMR-G but differs in fixed output voltage settings. The series emphasizes low quiescent current and compact packaging for space-constrained portable electronics.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

XC9141B33CMR-G offers identical electrical characteristics except for a 3.3 V fixed output instead of 3.9 V. XC9141A30CMR-G provides a 3.0 V output with comparable performance metrics. Verify pin compatibility and output voltage requirements before substitution.
