AS1328A-BQFT-12

Overview

The AS1328A-BQFT-12 is a synchronous buck switching regulator IC manufactured by ams-OSRAM USA INC. It provides a fixed positive output voltage of 1.2V with a maximum output current capacity of 3A. The device operates at a switching frequency of 1.5MHz and utilizes a 16-WFQFN package with an exposed pad for thermal management.

Feature Summary

• Integrates synchronous rectification for improved efficiency
• Delivers stable fixed voltage regulation
• Supports high current output applications

Applications

• Portable electronic devices requiring efficient power conversion
• Embedded systems utilizing low-voltage logic
• Battery-powered equipment needing compact regulators

Procurement Notes

Verify the specific suffix '-12' confirms the 1.2V fixed output variant. Confirm the 16-WFQFN package type matches your PCB footprint. Ensure thermal design accounts for the exposed pad to maintain reliability under load conditions.

Selection Notes

Select this component when a fixed 1.2V rail is required from a higher input voltage source. The 3A current rating suits moderate power loads. The 1.5MHz frequency allows for smaller external inductors compared to lower-frequency alternatives.

Part Context

This part belongs to the PMIC - Voltage Regulators - DC DC Switching Regulators category. It is designed for space-constrained applications where high efficiency and small form factor are critical requirements for system performance.

Replacement Considerations

Check for compatible 1.2V, 3A synchronous buck regulators in 16-pin packages. Verify pinout compatibility and thermal characteristics before substituting with other manufacturers' equivalents.
