Overview
The AS1382A-BWLT-15 is a high-efficiency DC-DC step-down converter manufactured by ams OSRAM. It provides a fixed positive output voltage of 1.5V with a maximum output current capability of 1A. The device operates from an input voltage range starting at 2.7V, making it suitable for battery-powered applications. Packaged in a compact 6-UFBGA or WLCSP format, this regulator integrates switching elements to minimize external component requirements while maintaining stable performance under varying load conditions.
Feature Summary
- Delivers a fixed 1.5V output voltage with 1A current capacity
- Operates efficiently from low input voltages starting at 2.7V
- Utilizes a compact WLCSP package for space-constrained designs
Applications
- Battery-powered portable electronics
- Low-voltage digital logic supply regulation
- Space-constrained mobile devices
Procurement Notes
Verify the specific manufacturer source, as distribution channels may list components under various brand names including OSRAM Opto Semiconductors. Confirm the package type matches the design requirement, as WLCSP handling requires specialized assembly processes. Check for recent discontinuation notices or lifecycle status updates before finalizing procurement plans.
Selection Notes
Select this component when a fixed 1.5V rail is required from inputs above 2.7V. Ensure the PCB layout supports the small footprint and thermal characteristics of the WLCSP package. Verify that the application does not require adjustable output voltages, as this model provides a fixed setting.
Part Context
This part belongs to the family of high-efficiency buck switching regulators designed for mobile and portable applications. It represents a solution for stepping down higher battery voltages to lower logic levels efficiently. The technology focuses on minimizing power loss and physical size compared to linear regulators.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official distributor databases for cross-reference information based on electrical specifications and package compatibility.
