AS1117-BQFT

Overview

The AS1117-BQFT is a linear LED driver IC manufactured by ams-OSRAM USA INC. It features a supply voltage range of 2.7V to 5.5V and supports an operating temperature range of -40°C to 85°C (TA). The device is housed in a 24-TQFN (4x4) package with an exposed pad, designed for surface mount installation. It draws a supply current of 335 mA.

Feature Summary

• Linear LED driver configuration
• Surface mount TQFN packaging

Applications

• Display drivers
• LED lighting systems

Procurement Notes

Verify the manufacturer designation carefully, as search results indicate potential confusion between ams-OSRAM USA INC. and ams OSRAM AG for similar part numbers. Confirm the specific datasheet version matches the 24-TQFN package and 2.7V-5.5V supply range specifications before procurement to ensure compatibility with system requirements.

Selection Notes

Select this component for applications requiring a linear LED driver topology within a compact 24-pin footprint. Ensure the input voltage remains within the 2.7V to 5.5V window and that thermal management accommodates the 335 mA supply current draw in the specified operating temperature range.

Part Context

This component belongs to the LED driver category under Power Management ICs (PMIC). It is distinct from other ams-OSRAM parts like the AS1122B or AS1111C, which feature different channel counts and pin configurations. The AS1117-BQFT is specifically identified in distributor listings as a display driver solution.
