DC DC Switching Controllers Procurement Notes
Verify the specific suffix (e.g., CF vs IS) against the manufacturer's datasheet to confirm temperature grade and package type. Ensure compatibility with the intended switching frequency and output voltage requirements before procurement.
DC DC Switching Controllers Selection Notes
Select this component when a compact, high-current buck regulator is required for 5V to 26V input applications. Consider the 270kHz fixed frequency for EMI management and the need for external compensation components as specified in the design guidelines.
DC DC Switching Controllers Part Context
This part belongs to the LTC1735 family of synchronous buck regulators. It is designed for applications requiring efficient power conversion from higher bus voltages to lower logic or battery voltages. Evaluation boards such as DC247A are available for performance verification.
DC DC Switching Controllers Replacement Considerations
Check for direct pin-compatible alternatives within the Analog Devices portfolio that match the 9A current rating and 26V maximum input specification. Verify equivalent thermal performance and switching frequency characteristics.
