Overview
The AS1328A-BQFT-AD is a buck switching regulator IC manufactured by ams-OSRAM USA INC. It provides a positive adjustable output voltage ranging from 0.6V to the input supply, delivering up to 3A of output current. The device is housed in a 16-WFQFN package with an exposed pad, designed for surface-mount assembly. This component functions as a step-down DC-DC converter suitable for power management applications requiring efficient voltage regulation and compact form factors.
Feature Summary
- Integrates a high-efficiency synchronous buck converter topology
- Provides adjustable output voltage starting at 0.6V
- Supports continuous output current up to 3A
- Utilizes a compact 16-pin WQFN package with thermal pad
Applications
- Portable battery-powered devices
- Industrial control systems
- Consumer electronics power supplies
Procurement Notes
Verify the specific suffix 'AD' against the manufacturer's official documentation to confirm exact electrical characteristics and packaging details. Ensure compatibility with your PCB footprint and thermal design requirements before procurement. Cross-reference the datasheet for any recent revisions that may affect performance or pinout definitions.
Selection Notes
Select this component when a compact, high-current step-down solution is required. The adjustable output range allows flexibility in system design. Consider the thermal performance of the exposed pad for heat dissipation in enclosed environments. Verify input voltage ranges match the application's power source constraints.
Part Context
This part belongs to the AS1328 series of switching regulators from ams-OSRAM. The series includes variants with different fixed output voltages (e.g., -12, -18) and adjustable versions. The AS1328A variant specifically denotes the adjustable output configuration within this family of power management integrated circuits.
Replacement Considerations
Check for direct substitutes such as AS1328C-BQFT-AD if updated revisions are available. Other compatible parts may include similar 3A buck converters from different manufacturers, but pinout and thermal characteristics must be verified.
