Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix DER-G against the manufacturer's official datasheet to confirm the exact package type and tape-and-reel specifications. Ensure the required output voltage matches the fixed 1.7V variant, as other suffixes indicate different voltages. Confirm RoHS compliance status directly with the supplier documentation prior to ordering.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.7V output is required from a 2V to 6V input source. The 600mA current capacity suits moderate load applications. Consider the 3MHz switching frequency for smaller external inductor and capacitor sizes compared to lower-frequency alternatives. Verify thermal performance requirements for the UFDFN package in the target enclosure.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9235 series of synchronous buck converters manufactured by Torex Semiconductor Ltd. The series offers various fixed output voltages and packages.
