Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix DER-G against the official Torex datasheet to confirm the package type and tape-and-reel specifications. Ensure compatibility with the required output voltage tolerance and thermal performance for the target application environment before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.9V output is required from a 2V-6V input source. The 3.45MHz switching frequency allows for smaller inductors and capacitors compared to lower-frequency alternatives. Ensure the load current does not exceed 600mA and that the PCB layout supports the thermal requirements of the PDSO6 package.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9237 series of synchronous buck converters. The series is characterized by high efficiency and compact packaging, designed for applications where space and power consumption are critical factors. The XC9237C29DER-G specifically offers a fixed 2.9V output, distinguishing it from adjustable or other fixed-voltage variants in the same family.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes may include other XC9237 series variants with different output voltages if the voltage requirement can be adjusted via external components, though fixed-output parts are generally not pin-to-pin compatible with different voltages without circuit modification. Check for XC9237A or XC9237B series equivalents if higher performance or different packages are needed.
