Procurement Notes
This component is currently listed as discontinued or no longer manufactured by the producer. Verify availability through authorized distributors or secondary market suppliers. Tariff implications may apply if shipping to the United States; confirm specific customs duties before finalizing procurement plans.
Selection Notes
Select this part when designing circuits requiring a compact boost solution for low-voltage inputs. Ensure the design accommodates the 8-UFDFN package constraints. Confirm that the required load current does not exceed the 1A limit and that the output voltage falls within the 5V to 18V adjustable range.
Part Context
The AS1345C-BTDT-AD belongs to the Voltage Regulators - DC DC Switching Regulators class. It is designed for power management tasks where space efficiency and compatibility with common battery chemistries are prioritized over high-power delivery.
Replacement Considerations
As this part is discontinued, identify functional equivalents from the same manufacturer's current portfolio or cross-reference with other boost regulators offering similar 2.9V input and 1A output capabilities in comparable packages.
