Overview
The AS1104-T is a high-efficiency direct LED driver IC manufactured by ams-OSRAM USA INC. It features four independent output channels, each capable of delivering up to 40mA. The device supports both analog current adjustment and external PWM dimming for precise control. It operates within a voltage range of 0.15V to 3.6V per channel and functions reliably across an operating temperature range of -40°C to 85°C.
Feature Summary
- Four-channel architecture with individual 40mA outputs
- Supports analog current adjustment and external PWM dimming
- Designed for high efficiency in direct LED driving applications
Applications
- LED backlighting systems
- General illumination control
- Display brightness management
Procurement Notes
Verify the specific suffix 'T' against official datasheets to confirm tape-and-reel packaging configuration. Ensure compatibility with system voltage levels between 0.15V and 3.6V. Confirm thermal requirements align with the -40°C to 85°C operational range. Cross-reference pinouts with target PCB layout specifications before integration.
Selection Notes
Select this component when multi-channel LED control with mixed analog and PWM dimming is required. It suits designs needing compact power management solutions for displays or lighting. Evaluate thermal dissipation needs given the 40mA per channel limit. Consider interface compatibility for external PWM signals if dynamic brightness adjustment is necessary.
Part Context
The AS1104 belongs to ams-OSRAM's portfolio of power management integrated circuits. It serves as a dedicated driver for light-emitting diodes, offering a compact solution for managing multiple LED strings. The device integrates control logic and output drivers into a single package, simplifying circuit design for consumer electronics and industrial lighting applications.
Replacement Considerations
Consult official cross-reference tools for compatible alternatives. Verify electrical parameters such as output current and dimming methods match original requirements. Check package dimensions and pin configurations for mechanical compatibility. Review manufacturer documentation for any functional differences in control interfaces.
