Overview
The AS1382A-BWLT-AD is a buck switching regulator integrated circuit manufactured by ams OSRAM. It features an adjustable positive output voltage starting at 0.58V and supports a maximum output current of 1A. The device operates with a fixed switching frequency of 4 MHz and accepts input voltages up to 5.5V. It is housed in a 6-wafer-level chip-scale package (WLCSP) and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates a high-frequency 4 MHz switching regulator for compact power solutions
- Provides adjustable positive output voltage capability down to 0.58V
- Supports up to 1A continuous output current for demanding loads
Applications
- Portable electronic devices requiring efficient step-down conversion
- Battery-powered systems needing stable low-voltage regulation
- Embedded circuits utilizing WLCSP form factors for space constraints
Procurement Notes
Verify the specific suffix AD against official datasheets to confirm pinout and electrical characteristics, as variations may exist. Confirm RoHS compliance status directly with the manufacturer or authorized distributors before integration. Ensure the supply chain source is authorized to guarantee component authenticity and traceability.
Selection Notes
Select this component when a small footprint and high switching frequency are required to minimize external passive component size. The adjustable output range allows flexibility for various logic levels. Verify that the input voltage does not exceed the 5.5V absolute maximum rating during operation.
Part Context
This part belongs to the AS1382 series of power management ICs from ams OSRAM. These regulators are designed for mobile and portable applications where efficiency and board space are critical. The series typically includes variants with different output configurations and packaging options.
Replacement Considerations
Check for direct substitutes within the AS1382 family, such as the AS1382A-BWLT-AD without suffix variations if available. Cross-reference with other 1A buck regulators in WLCSP packages from compatible manufacturers, ensuring matching input/output specifications and thermal performance.
