Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix DER-G against the official datasheet to confirm package type and tape/reel specifications. Ensure compatibility with your PCB footprint, specifically the USP-C-EP-6 or equivalent 6-UFDFN dimensions. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5.2 V output is required from a variable or low-voltage source up to 6 V. The 500 mA output current suits moderate load applications. Consider the 3 MHz switching frequency for smaller external passive components compared to lower-frequency alternatives. The synchronous design offers better efficiency than non-synchronous counterparts at similar currents.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9142 series of 0.8 A step-up DC/DC converters. The series includes various output voltage options and package types. The XC9142 family is designed for green operation compatibility and features load disconnection functions in some variants. This specific model focuses on the 5.2 V fixed output configuration.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations
