Overview
The A6270KLPTR-T is a linear PWM LED driver IC manufactured by Allegro MicroSystems. It features a single output and operates within a supply voltage range of 5V to 50V DC. The device supports both analog and PWM dimming functions for precise light control. It is housed in a 16-pin eTSSOP package with an exposed pad, designed for surface-mount applications. The component is rated for automotive use and complies with the AEC-Q100 qualification standard.
Feature Summary
- Supports PWM and analog dimming for flexible brightness control
- Automotive-grade reliability with AEC-Q100 certification
- Linear regulation architecture for stable current drive
Applications
- Automotive exterior lighting systems
- Interior cabin illumination
- General high-brightness LED backlighting
Procurement Notes
Verify the specific suffix 'KLPTR-T' against the official datasheet to confirm package type and tape-and-reel specifications. Ensure the design accounts for thermal dissipation requirements inherent to linear regulators. Confirm that the application voltage remains within the specified 5V to 50V operational limits to prevent device damage.
Selection Notes
Select this component when a single-channel linear solution is required for automotive or industrial LED applications. It is suitable for designs prioritizing simplicity and cost-efficiency over high-frequency switching topologies. Consider the thermal performance of the eTSSOP package relative to the expected load current and ambient temperature conditions.
Part Context
This part belongs to the A6270 series of LED drivers from Allegro MicroSystems. It shares functional similarities with other members like the A6271 but differs in topology, as the A6271 utilizes a DC-DC controller rather than linear regulation. This distinction makes the A6270 appropriate for lower-voltage drop applications compared to its switching counterparts.
Replacement Considerations
Direct replacements include the A6270KLPTR-T-1 variant. Designers should verify pinout compatibility and thermal characteristics when substituting with other linear LED drivers from the same manufacturer family.
