Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance as per manufacturer standards. Confirm the 'DER' designation corresponds to the USP-C-EP-6 package type. Ensure the part number matches the required 2.1 V output specification. Cross-reference with official Torex documentation to validate availability and lead times through authorized distributors.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.1 V output is required from a 1.8 V to 6 V input source. The 600 mA current capability suits moderate load applications. The 3 MHz switching frequency allows for smaller external inductors compared to lower-frequency alternatives. Consider the USP-C-EP-6 package constraints for PCB layout design.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9237 series of synchronous step-down converters. The series offers various fixed output voltages and packages. The G suffix typically denotes environmental compliance. The DER suffix specifies the small outline package variant used in space-constrained designs.
