Overview
The AS1328B-BQFT-12 is a synchronous buck switching regulator IC from ams-OSRAM USA INC. It provides a fixed positive output voltage of 1.2V with a maximum output current of 3A. The device utilizes a 16-WFQFN package with an exposed pad for thermal management. Designed for high efficiency, it operates as a DC-DC converter suitable for space-constrained applications requiring stable power regulation.
Feature Summary
- Synchronous buck topology for high efficiency
- Fixed 1.2V output voltage configuration
- Capable of delivering up to 3A load current
- Compact 16-pin WQFN package design
Applications
- Portable electronic devices
- Battery-powered systems
- Embedded control circuits
- General-purpose power regulation modules
Procurement Notes
Verify the exact suffix '12' confirms the fixed 1.2V output variant. Confirm the 'BQ' designation indicates automotive qualification requirements if applicable to your specific deployment environment. Ensure the 16-WFQFN footprint matches your PCB layout constraints and thermal dissipation capabilities before finalizing procurement orders.
Selection Notes
Select this component when a fixed 1.2V rail is required at currents up to 3A in a small form factor. Compare against adjustable variants like the AS1328B-BQFT-AD if programmable output is needed. Evaluate thermal performance based on the exposed pad requirement and ensure input voltage ranges align with your system's power source specifications.
Part Context
This part belongs to the AS1328 series of synchronous buck regulators. It shares the core architecture with other variants in the family but differs in output configuration. The 'BQ' suffix typically denotes enhanced reliability or automotive-grade processing compared to standard commercial versions within the same manufacturer lineup.
Replacement Considerations
The AS1328B-BQFT-AD serves as a functional alternative if adjustable output voltage is acceptable instead of the fixed 1.2V setting. Verify pin compatibility and thermal characteristics when substituting with other 16-WFQFN buck regulators from different manufacturers.
