Overview
The AS1110-BSSU is a linear LED driver IC from the AS1110 series, manufactured by ams OSRAM. It features 16 outputs with a maximum output voltage of 15V and an output current of 100mA per channel. The device operates on a supply voltage range of 3V to 5.5V and supports a clock frequency of 50MHz. Packaged in a 24-SSOP housing, it is designed for signboard applications and functions within a temperature range of -40°C to 85°C.
Feature Summary
- Integrates a shift register topology for efficient serial data input and parallel output control.
- Supports PWM dimming operations for precise brightness adjustment across all channels.
- Features internal switches to manage individual LED channel connections directly.
Applications
- Signboard illumination systems
- Static LED display matrices
- Architectural lighting control
Procurement Notes
Verify component authenticity through authorized distributors as this part is officially discontinued. Confirm package integrity upon receipt, noting the 24-SSOP form factor. Check datasheet revisions for any historical manufacturing changes prior to integration into new designs.
Selection Notes
Select this component for fixed-current linear driving requirements where low cost and simple interface are prioritized. Ensure the application does not exceed the 15V output limit or require higher efficiency switching topologies. Validate thermal management capabilities for the SSOP package under full load conditions.
Part Context
This IC belongs to the AS1110 family of LED drivers, which are optimized for high-density LED arrays. The BSSU suffix indicates a tube packaging variant, distinct from the reel-based BSST version. It serves as a legacy solution for static lighting control before more advanced multiplexed drivers became standard.
Replacement Considerations
Public confirmed substitute part numbers are not available for this discontinued component. Designers should evaluate newer ams OSRAM LED driver families or generic compatible shift-register drivers that match the 24-SSOP footprint and electrical specifications.
FAQ
What is the maximum output voltage supported by the AS1110-BSSU?
The device supports a maximum output voltage of 15V per channel.
Does the AS1110-BSSU support dimming functionality?
Yes, it supports PWM dimming operations for controlling LED brightness.
