Overview
The AS1310-BTDT-25 is a synchronous buck-boost switching regulator manufactured by ams OSRAM. It operates with an input voltage range of 2.7 V to 5.5 V and provides a fixed output voltage of 2.5 V. The device delivers a maximum output current of 300 mA at a switching frequency of 500 kHz. It supports continuous conduction mode (CCM) and discontinuous conduction mode (DCM). The component functions within a temperature range of -40°C to +85°C and is housed in a TDFN-10 package.
Feature Summary
- Integrated synchronous buck-boost topology for flexible power conversion
- Fixed 2.5 V output configuration for stable supply rails
- Supports both continuous and discontinuous conduction modes
Applications
- Portable electronic devices requiring stable low-voltage regulation
- Battery-powered systems with varying input levels
- Embedded control circuits needing 2.5 V logic supplies
Procurement Notes
Verify the exact suffix BTDT-25 against official datasheets to confirm pinout and thermal specifications. Confirm availability status as distribution channels may list discontinued or limited stock items. Ensure compatibility with your PCB footprint, specifically the TDFN-10 package dimensions. Cross-reference manufacturer part numbers directly from ams OSRAM documentation to avoid counterfeit components.
Selection Notes
Select this component when a fixed 2.5 V output is required from a single-cell lithium battery or USB source. The synchronous design offers higher efficiency compared to non-synchronous alternatives. Verify that the 300 mA load requirement does not exceed the thermal limits of the TDFN-10 package in your specific enclosure environment.
Part Context
This part belongs to the AS13xx series of power management ICs from ams OSRAM. These regulators are designed for mobile and portable applications where space and efficiency are critical constraints. The series typically integrates power switches and control logic into a compact form factor suitable for dense PCB layouts.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided reference data. Consult ams OSRAM technical support or authorized distributor cross-reference tools for verified equivalents.
