XC9291B11E1R-G

Voltage Regulators - DC DC Switching Regulators Overview

The XC9291B11E1R-G is a non-isolated synchronous step-down DC/DC converter manufactured by Torex Semiconductor. It operates with an input voltage range of 2.5 V to 6 V and provides a fixed output voltage of 1.1 V at a maximum output current of 600 mA. The device utilizes HiSAT-COT control for stable operation without external compensation capacitors. It is housed in an ultra-compact WLP-5-8 package measuring 0.96 mm x 0.88 mm x 0.33 mm, suitable for space-constrained surface-mount applications.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix E1 against official Torex documentation to confirm the exact output voltage configuration. Ensure compatibility with the required WLP-5-8 soldering profile during assembly. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status through the latest datasheet revision.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.1 V output is required within a 6 V input limit. The WLP-5-8 package is optimal for high-density PCB layouts where LGA alternatives are too large. Consider the 600 mA current rating against peak load requirements. Verify that the operating temperature range meets the environmental constraints of the target application.

Voltage Regulators - DC DC Switching Regulators Part Context

This model belongs to the XC9291 series of extremely small step-down DC/DC converters. The series is characterized by its integration of synchronous rectification and HiSAT-COT control. Other variants in the family offer different fixed output voltages while maintaining similar electrical characteristics and package options.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Consult the official XC9291 series datasheet for direct pin-compatible substitutes with different output voltages. Verify that alternative packages such as LGA-6B01 meet spatial constraints if cross-package substitution is considered.
