Procurement Notes
Verify the specific suffix (BTDR) confirms the 10TDFN package and 1.25A rating. Confirm RoHS compliance status via the manufacturer datasheet. Ensure the supplier provides the official data sheet for electrical parameter validation before procurement.
Selection Notes
Select this component when a compact synchronous boost solution is required for low-voltage inputs. The 1MHz frequency allows for smaller external inductors compared to lower-frequency alternatives. Verify that the 1.25A switch current meets the peak load requirements of the target application circuit.
Part Context
This part belongs to the ams OSRAM voltage regulator portfolio, specifically designed for DC-DC conversion applications. It complements other power management ICs by offering high efficiency in a small form factor suitable for space-constrained portable designs.
Replacement Considerations
Check for direct pin-compatible substitutes within the same family. Verify if alternative regulators offer higher current ratings or different input voltage ranges if system requirements have changed.
