Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence when ordering. Confirm the TSSOP-EP-20 package availability matches your assembly requirements. Ensure the 1 MHz fixed frequency variant aligns with your EMI constraints. Cross-reference the manufacturer part number with official Analog Devices documentation to avoid counterfeit components during procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a wide input voltage range up to 40 V is required alongside a buck-boost capability. The fixed 1 MHz frequency simplifies design compared to programmable variants. Consider the thermal performance of the exposed pad package for high-current applications. Verify that the 2 A current rating meets the peak load demands of the target system without exceeding thermal limits.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LTC3115 family of synchronous Buck-Boost converters. It is designed for applications where input voltage may rise above or fall below the desired output voltage. The device integrates power switches and control logic into a compact package, reducing the need for external diodes and complex gate drive circuits found in older topologies.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for direct pin-compatible upgrades within the LTC3115 series. Verify if alternative packages like EFE offer different thermal characteristics. Ensure any substitute maintains the 1 MHz fixed frequency and 2 A current capability. Confirm that the replacement supports the same 40 V maximum input and output voltage ratings.
