AS1328B-BQFT-15

Overview

The AS1328B-BQFT-15 is a Buck Switching Regulator IC manufactured by ams OSRAM USA INC. It provides a positive fixed output voltage of 1.5V with a maximum output current capability of 3A. The device is housed in a 16-WFQFN package featuring an exposed pad, designed for surface-mount applications. As a DC-DC switching controller, it regulates power conversion efficiently within its specified electrical parameters.

Feature Summary

• Integrated buck switching regulator topology
• Fixed positive output voltage regulation
• High current delivery capability

Applications

• Portable electronic devices requiring stable low-voltage power rails
• Battery-powered systems needing efficient step-down conversion
• Embedded circuits utilizing fixed 1.5V logic levels

Procurement Notes

Verify the specific suffix '15' confirms the 1.5V fixed output variant during procurement. Ensure the 16-WFQFN package type matches the target PCB footprint. Confirm the manufacturer designation as ams OSRAM USA INC. to avoid counterfeit components. Cross-reference the datasheet for thermal dissipation requirements associated with the exposed pad design.

Selection Notes

Select this component when a fixed 1.5V output is required without external resistor programming. The 3A current rating suits moderate load applications. Consider the 16-WFQFN package for space-constrained designs. Verify input voltage ranges against the system supply before integration.

Part Context

This part belongs to the AS1328 series of voltage regulators from ams OSRAM. The series includes various output voltage options distinguished by their ordering suffixes. The BQFT-15 specifically denotes the 1.5V fixed version in the TQFN/WFQFN form factor.

Replacement Considerations

Check for other AS1328 variants with different output voltages if 1.5V is not suitable. Verify pin compatibility with alternative buck converters offering similar 3A current ratings and 16-pin QFN packages.
