Overview
The AS1345A-BWLT-AD is a high-efficiency DC-DC step-up converter manufactured by ams OSRAM. It integrates an internal N-channel and P-channel output isolation switch to function as a boost switching regulator IC with positive adjustable output. The device delivers up to 1A of current and supports fixed output voltages including 5V, 12V, 15V, and 17V depending on the specific suffix variant. It operates within a temperature range of -40°C to +85°C and is housed in an 8-UFBGA WLCSP package.
Feature Summary
- Integrates internal N-channel and P-channel output isolation switches for efficient power conversion
- Provides positive adjustable or fixed voltage output configurations
- Designed for high efficiency in compact surface-mount applications
Applications
- Patient monitoring systems for measuring vital signs such as heart rate and blood pressure
- Oxygen saturation measurement circuits
- Portable medical devices requiring reliable voltage regulation
Procurement Notes
Verify the exact output voltage configuration required, as the base part number may correspond to different fixed voltage variants (e.g., 5V, 12V, 15V, 17V) indicated by suffixes. Confirm the package type is 8-UFBGA WLCSP and ensure the operating temperature range meets the application's environmental requirements of -40°C to +85°C before ordering.
Selection Notes
Select this component when a compact boost converter is needed for low-power portable electronics. Ensure the load current does not exceed the 1A rating. Consider the specific voltage variant suffix if a fixed output is preferred over an adjustable one. Verify compatibility with the target PCB footprint for the 8-WLCSP package.
Part Context
This component belongs to the AS1345 series of high-efficiency DC-DC step-up converters from ams OSRAM. These regulators are designed to provide stable power supply solutions for battery-operated devices. The series includes various output voltage options to suit different system requirements while maintaining a small form factor suitable for space-constrained designs.
Replacement Considerations
Check for compatible boost converters with similar 1A output current and WLCSP packaging. Ensure replacement parts support the same input voltage range and offer comparable efficiency at the target load conditions.
