Overview
The AS1323-BTTT-27 is a fixed-output step-up switching regulator manufactured by ams OSRAM. It provides a fixed output voltage of 2.7V with a maximum switch current of 1A. The device features synchronous rectification for high efficiency and is housed in a SOT-23-5 thin package. It operates within a temperature range of -40°C to 85°C and includes an enable function. The component is currently listed as obsolete or no longer manufactured.
Feature Summary
- Synchronous step-up switching regulator architecture
- Fixed 2.7V output configuration
- Integrated enable control functionality
Applications
- Battery-powered portable devices requiring voltage boosting
- Systems needing a stable 2.7V supply from lower input sources
- Compact electronics utilizing SOT-23-5 surface mount packaging
Procurement Notes
This component is officially marked as obsolete or no longer manufactured by ams OSRAM. Verify availability through secondary market distributors, noting potential tariff implications if shipping to the United States. Confirm end-of-life status directly with suppliers before design finalization.
Selection Notes
Select this part only if a fixed 2.7V output at up to 1A is required in a SOT-23-5 package. Due to its obsolete status, alternative components with similar electrical specifications and pinouts should be evaluated for new designs. Ensure compatibility with existing PCB footprints if replacing active units.
Part Context
The AS1323 series represents a family of efficient step-up regulators from ams OSRAM. The BTTT suffix indicates specific tape-and-reel packaging and output voltage variants. This model specifically targets applications requiring a precise 2.7V rail, distinguishing it from other voltage options in the same product line.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Designers must identify cross-compatible parts based on functional equivalence, such as other 2.7V synchronous boost regulators in SOT-23-5 packages, while verifying pinout compatibility.
