AS1383-BWLT-AD

Overview

The AS1383-BWLT-AD is a boost switching regulator IC manufactured by ams-OSRAM USA INC. It features a synchronous step-up architecture designed for positive adjustable voltage regulation. The device provides a single output capable of delivering up to 200mA. It operates with an adjustable output voltage starting from 2.7V. The component is packaged in a compact 6-UFBGA, also known as WLCSP, suitable for space-constrained applications.

Feature Summary

• Synchronous step-up architecture for efficient power conversion
• Positive adjustable voltage regulation capability
• Compact 6-UFBGA (WLCSP) package design

Applications

• Portable electronic devices requiring step-up voltage conversion
• Battery-powered systems needing regulated higher voltage rails
• Space-constrained circuit boards utilizing WLCSP packaging

Procurement Notes

Verify the exact manufacturer part number against official ams-OSRAM documentation to ensure authenticity. Confirm that the 6-UFBGA package matches your PCB footprint requirements. Check for any specific ordering suffixes that may indicate tape-and-reel versus bulk packaging options. Ensure compatibility with your system's input voltage range and load current demands before finalizing procurement.

Selection Notes

Select this component when a synchronous boost converter is required for efficient step-up applications. Consider the 200mA output current limit and the minimum 2.7V output voltage constraint. The WLCSP package is ideal for high-density designs. Evaluate thermal performance and efficiency requirements relative to the synchronous topology benefits compared to non-synchronous alternatives.

Part Context

This part belongs to the family of power management integrated circuits offered by ams-OSRAM USA INC. It specifically addresses the need for efficient DC-DC conversion in portable and battery-operated electronics. The synchronous boost architecture distinguishes it from simpler linear regulators or non-synchronous switching solutions, offering improved efficiency at lower output currents.
