Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against official Torex documentation to confirm pinout compatibility and electrical tolerances. Ensure the ordering code matches the required output voltage and package type. Cross-reference datasheet revisions to confirm RoHS compliance status before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.8V rail is required from a 2V to 6V source. The choice between 1.2MHz and 3.0MHz switching frequencies should be based on inductor size constraints versus transient response requirements. Verify that the load current does not exceed the 600mA limit under all thermal conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9235 series of synchronous buck converters. The 'A' designation indicates a 2.0V minimum input voltage, while 'H' specifies the 2.8V fixed output.
