Overview
The LDS8141-002-T2 is a linear LED driver IC from IXYS Integrated Circuits Division, housed in a 16-TQFN (3x3) package. It features analog and PWM dimming capabilities with a maximum output current of 32mA per channel. The device operates on a supply voltage ranging from 2.5V to 5.5V and supports an operating junction temperature range of -40°C to 125°C.
Feature Summary
- Supports both analog and PWM dimming control methods for precise LED brightness regulation.
- Integrates linear topology for stable current delivery without external switching components.
- Capable of handling wide ambient temperature variations suitable for demanding environments.
Applications
- General illumination systems requiring constant current drive
- Portable electronic devices with limited power budgets
- Indicator lighting circuits
Procurement Notes
Verify the specific suffix T2 indicates tape and reel packaging when ordering. Confirm that the manufacturer designation remains IXYS Integrated Circuits Division, noting potential corporate restructuring into Littelfuse. Ensure compatibility with 16-TQFN footprints during PCB layout review.
Selection Notes
Select this component for applications requiring low-profile linear regulation rather than switched-mode topologies. The 32mA output limit suits low-power LEDs. Verify that the 2.5V minimum supply voltage aligns with the system's battery or rail specifications before finalizing the design.
Part Context
This part belongs to the IXYS PowerLite series of LED drivers. It is distinct from the discontinued LDS8724 boost converter and the LDS8640 charge pump variants. The LDS8141 utilizes a linear architecture, differentiating it from higher-power switching counterparts in the same product family.
Replacement Considerations
No direct public substitute part numbers are confirmed for this specific model in the provided documentation. Designers should evaluate generic linear LED drivers with matching 32mA output and 16-TQFN packaging if sourcing becomes unavailable.
FAQ
What is the maximum output current for the LDS8141-002-T2?
The maximum output current is 32mA.
Does the LDS8141 support PWM dimming?
Yes, the device supports both analog and PWM dimming functions.
