Overview
The AS1313-BTDM-30 is a synchronous buck converter manufactured by ams OSRAM. It provides a fixed 3.0V output with a maximum current of 150mA. The device operates within an input voltage range suitable for single-cell lithium-ion battery applications. It features a switching frequency that allows for compact external component selection. The IC is housed in an MLPD EP-8 surface-mount package, designed for efficient power conversion in space-constrained portable electronics.
Feature Summary
- Synchronous step-down topology for high efficiency
- Fixed 3.0V output voltage regulation
- Compact MLPD EP-8 surface-mount package
Applications
- Single-cell lithium-ion battery powered devices
- Portable consumer electronics
- Battery-operated instrumentation
Procurement Notes
Verify the obsolete status and end-of-life notifications directly with ams OSRAM or authorized distributors before design finalization. Confirm availability of equivalent replacement components from the same product family to ensure long-term supply chain stability for production runs.
Selection Notes
Select this part when a fixed 3.0V output at up to 150mA is required from a single-cell lithium source. The synchronous design offers better efficiency than asynchronous alternatives. Ensure the application environment supports the thermal characteristics of the MLPD EP-8 package without excessive heatsinking requirements.
Part Context
This component belongs to the AS131x series of synchronous buck converters from ams OSRAM. These regulators are engineered for low-power portable applications requiring high efficiency and small footprint. The series typically includes variants with different fixed output voltages to accommodate various logic levels and subsystem requirements in mobile devices.
Replacement Considerations
Check for other AS131x series parts with compatible output voltages and current ratings. Verify pinout compatibility if substituting within the same manufacturer's portfolio to minimize PCB redesign efforts.
