AS1328B-BQFT-18

Overview

The AS1328B-BQFT-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 current capacity of 3A in a single output configuration. The device utilizes a 16-WFQFN package featuring an exposed pad for thermal management. As a switching regulator, it converts input voltage to the specified lower DC level efficiently.

Feature Summary

Fixed output voltage regulation
High current delivery capability
Switching topology operation

Applications

General power supply systems requiring stable 1.8V rails
Embedded electronics needing efficient step-down conversion
Portable devices utilizing buck regulator architectures

Procurement Notes

Verify the specific suffix BQFT and output voltage code 18 against official datasheets to ensure compatibility. Confirm package type and pinout alignment with design requirements before procurement.

Selection Notes

Select this component when a fixed 1.8V output at up to 3A is required. Ensure input voltage ranges match application needs and thermal design accommodates the WFQFN package dissipation characteristics.
