Overview
The AS1313-BTDM-18 is a Buck Switching Regulator IC manufactured by ams-OSRAM USA INC. It provides a positive fixed output voltage of 1.8V with a maximum output current capability of 150mA. The device features a single output configuration and is housed in an 8-UFQFN package with an exposed pad, designated as the BTDM suffix.
Feature Summary
- Integrated buck switching regulator topology for efficient DC-DC conversion
- Fixed 1.8V output voltage specification
- Compact 8-pin UFQFN package design
Applications
- Portable electronic devices requiring stable low-voltage power rails
- Battery-powered systems utilizing buck conversion
- Embedded circuits needing regulated 1.8V supply
Procurement Notes
Verify the complete part number including the BTDM suffix to ensure correct output voltage and package type. Confirm that the 1.8V fixed output aligns with system requirements. Check the 8-UFQFN footprint compatibility during PCB layout. Ensure thermal management accounts for the exposed pad design. Validate input voltage ranges against specific application needs before ordering.
Selection Notes
Select this component when a fixed 1.8V output is required without external resistor programming. The integrated buck topology suits space-constrained designs. Consider the 150mA current limit for load requirements. The exposed pad package aids thermal dissipation. Verify compatibility with existing control signals if synchronous operation is needed.
Part Context
This regulator belongs to ams-OSRAM's portfolio of power management solutions. While the manufacturer is known for optical components, this specific IC addresses electronic power regulation needs. The BTDM designation identifies the specific voltage and package variant within the broader AS1313 family.
Replacement Considerations
Check for direct pin-compatible alternatives offering identical 1.8V output and 150mA capacity. Verify equivalent switching frequency and efficiency characteristics. Ensure replacement parts support the same 8-UFQFN package outline. Confirm regulatory compliance matches original specifications.
