Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration against official manufacturer documentation. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary. Ensure the ordering part number matches the exact pinout and thermal pad requirements specified in the datasheet for your PCB layout.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.5 MHz switching frequency is required to optimize inductor size. Consider the 4 µA shutdown current for strict power budget constraints. Verify that the 36 V maximum input voltage aligns with your system's supply rails. Ensure the TQFN-EP-12 package fits within your available board space and thermal management capabilities.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MAX17290/MAX17292 family of switching regulators. While the MAX17290 offers variable frequency options, the MAX17292 variant specifically fixes the frequency at 2.5 MHz to simplify EMI filtering design. Both share similar control architectures but differ in switching frequency specifications and associated EMI performance characteristics.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The MAX17290ETCF+T serves as a functional alternative if variable switching frequency is acceptable instead of the fixed 2.5 MHz operation. Verify pin compatibility and control loop stability before substitution. Other Maxim integrated boost controllers may require significant circuit redesign due to differing interface or timing requirements.
