Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component authenticity through authorized Zilog distributors or certified suppliers. Confirm the specific suffix CMR-G matches the required reel packaging format. Ensure the supplier provides valid traceability documentation. Cross-reference the manufacturer part number against official Zilog catalogs to avoid counterfeit replacements. Validate that the received units match the specified SOT-25 package dimensions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3V output at up to 600mA is required from a higher input voltage source. The 1.2MHz switching frequency allows for smaller inductors and capacitors compared to lower-frequency alternatives. Consider the SOT-25 package size constraints during PCB layout. Verify that the input voltage range supports the intended application supply levels before integration.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the IXD3235 series of synchronous buck converters from Zilog. The series includes variants with different fixed output voltages, such as 1.5V and 1.8V models. These regulators are designed for space-constrained applications requiring efficient power management. The family shares common control logic and thermal characteristics while differing in output settings.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other IXD3235 variants with compatible pinouts but different output voltages, provided the system design accommodates the voltage change. Generic replacements must match the 600mA current rating, 1.2MHz frequency, and SOT-25 package. Verify electrical compatibility before substitution.
