Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix code against the official datasheet to confirm the exact output voltage and package variant. Ensure the ordering part number matches the required switching frequency configuration. Cross-reference the manufacturer's latest documentation for any updates to pinout or thermal specifications before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.55V output is required within a 6V input limit. Consider the manual mode switch feature if design requirements demand distinct noise performance at light versus heavy loads. Evaluate the 1.2MHz and 3.0MHz options based on external inductor size constraints and ripple current requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9237 series, which includes variants with different fixed output voltages and package types. The 'G' suffix typically indicates lead-free compliance. The 'CER' designation specifies the USP-6C package format. This series is designed for high-efficiency power conversion in space-constrained mobile applications.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other XC9237 variants with identical 2.55V output and USP-6C packaging. Verify that alternative parts support the same 1.8V minimum input voltage and 600mA current rating. Check compatibility of control mode switching capabilities if PWM/PFM transition is critical to the system design.
