DC DC Switching Controllers Procurement Notes
Verify component authenticity through authorized channels due to restricted availability status. Confirm the specific suffix matches the required tape-and-reel packaging configuration. Ensure compatibility with existing board layouts regarding the 14-pin SOIC footprint before procurement.
DC DC Switching Controllers Selection Notes
Select this component when designing systems requiring high efficiency in compact form factors. The 250kHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the 3.5V minimum input voltage aligns with the source supply characteristics.
DC DC Switching Controllers Part Context
This part belongs to the LTC1148 series of high-frequency buck converters. It shares functional similarities with the LTC1142 but offers single-output regulation. The HV designation indicates suitability for higher voltage input ranges common in industrial and portable applications.
DC DC Switching Controllers Replacement Considerations
LTC1148HVCS#PBF is the tube-packaged equivalent. Cross-reference with LTC1148 variants for pin-compatible solutions if reel quantities are unavailable.
