Overview
The AS1111B-BWLT is a linear LED driver IC manufactured by ams OSRAM. It features three independent output channels, each capable of delivering up to 40 mA. The device supports both analog and PWM dimming methods for precise brightness control. It operates within a supply voltage range of 0.15 V to 3.6 V. The component is housed in a compact 6-WLCSP package with dimensions of 1.17 mm x 0.77 mm. It is designed for surface mount installation and functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates three linear current sources for independent channel control
- Supports combined analog and pulse-width modulation dimming techniques
- Utilizes a miniature wafer-level chip-scale package for space-constrained designs
Applications
- LED backlighting systems
- General illumination circuits
Procurement Notes
Verify the End-of-Life status before finalizing design specifications, as this component may no longer be in active production. Confirm that the 6-WLCSP footprint matches your PCB layout requirements. Ensure compatibility with the specified 0.15 V to 3.6 V supply voltage range for your target application environment.
Selection Notes
Select this component when a low-voltage, multi-channel linear driver is required for small form-factor applications. The integrated analog and PWM dimming capabilities offer flexibility for brightness adjustment. Consider the thermal performance of the WLCSP package relative to the total current load of the three channels.
Part Context
This part belongs to the AS1111 series of LED drivers from ams OSRAM. These devices are engineered for portable electronics requiring efficient light management. The specific BWLT suffix indicates the wafer-level packaging and tape-and-reel shipping configuration suitable for automated assembly processes.
Replacement Considerations
Consult official manufacturer documentation for confirmed substitute part numbers. Verify pinout compatibility and electrical specifications if considering alternative components from other manufacturers.
