AS1111C-BDFT

Overview

The AS1111C-BDFT is a linear LED driver IC manufactured by ams OSRAM AG, designed for backlight and lighting applications. It features four independent output channels, each capable of delivering up to 40mA. The device supports both analog and PWM dimming methods for precise brightness control. Operating within a supply voltage range of 0.15V to 3.6V, it functions reliably across an ambient temperature range of -40°C to +85°C. The component is housed in an 8-MLPD (2x2) surface-mount package with exposed pads.

Feature Summary

Integrates four independent linear current sources for multi-channel LED control
Supports combined analog and pulse-width modulation dimming techniques
Includes internal switching capability for efficient power management

Applications

LED backlighting systems
General solid-state lighting fixtures

Procurement Notes

Verify the End-of-Life status confirmed on December 14, 2016, before initiating procurement. Confirm that the 8-MLPD (2x2) package footprint matches the target PCB design. Ensure compatibility with the specified 0.15V to 3.6V supply voltage range and operating temperature limits of -40°C to +85°C. Validate that the manufacturer ams OSRAM AG is the authorized source for this discontinued part number.

Selection Notes

Select this component when a low-voltage, four-channel linear driver is required for small-scale LED arrays. The integrated analog and PWM dimming capabilities allow for flexible brightness adjustment without external controllers. The compact 8-MLPD package suits space-constrained designs. Note that the device is no longer in active production, which may impact long-term supply availability.

Part Context

The AS1111C belongs to a family of LED drivers from ams OSRAM AG. This specific variant, AS1111C-BDFT, is distinguished by its tape-and-reel packaging format and the BDFT suffix indicating the specific reel configuration. It serves as a dedicated solution for driving multiple LEDs in parallel or series configurations within low-power applications.
