Procurement Notes

Verify the specific suffix against official documentation to confirm pinout compatibility and thermal characteristics. Ensure the selected variant matches the required operating temperature range and package style for your PCB layout. Cross-reference the manufacturer's latest datasheet to confirm active status and any recent design changes before finalizing procurement.

Selection Notes

Select this component when a single IC must support multiple DC/DC topologies such as Buck, Boost, or Cuk. It is suitable for designs requiring high efficiency with a 1.5A switch current capability. Consider the 250kHz fixed frequency for standard inductor sizing. Verify that the 30V maximum input voltage aligns with the system power source requirements.

Part Context

This part belongs to the LT1373 family of high-efficiency switching regulators. The HVIN suffix typically denotes a version optimized for higher input voltage capabilities compared to standard variants. It serves as a flexible solution for various power conversion needs within the Analog Devices PMIC portfolio.
