AS1345A-BWLT-12

Overview

The AS1345A-BWLT-12 is a boost switching regulator IC manufactured by ams-OSRAM USA INC. It provides a positive fixed output voltage of 12V with a single output channel capable of delivering up to 1A of current through its internal switch. The device is housed in an 8-UFBGA, WLCSP package. As part of the power management solutions offered by the manufacturer, this component is designed for efficient voltage step-up applications within compact electronic systems.

Feature Summary

• Integrates a boost switching regulator topology for efficient voltage conversion
• Provides a fixed positive output voltage of 12V
• Supports output currents up to 1A via an integrated switch
• Utilizes a compact WLCSP package for space-constrained designs

Applications

• Portable electronic devices requiring voltage boosting
• Battery-powered systems needing stable 12V supply
• Compact consumer electronics with limited board space

Procurement Notes

Verify the specific ordering suffix and package variant when sourcing. Confirm availability status as distribution channels may list obsolete or discontinued stock. Ensure compatibility with your PCB footprint for the 8-UFBGA WLCSP form factor. Cross-reference the manufacturer's latest documentation for any design-in updates or recommended operating conditions before finalizing procurement plans.

Selection Notes

Select this component when a fixed 12V output is required from a lower input voltage source. The 1A current capability suits moderate load applications. Consider the WLCSP package size if board real estate is critical. Verify that the input voltage range supports your system's battery or supply characteristics. Ensure thermal management aligns with the expected power dissipation in the target enclosure.
