Overview
The A8584KLPTR-T is a high-frequency synchronous buck regulator manufactured by Allegro MicroSystems. It operates within an input voltage range of 4V to 36V and delivers up to 3.5A of output current. The device features adjustable output voltages starting from 0.8V and supports switching frequencies between 250kHz and 2.4MHz. Packaged in a 16-lead TSSOP with an exposed pad, it is designed for automotive applications meeting AEC-Q100 standards and functions reliably across temperatures from -40°C to 125°C.
Feature Summary
- Synchronous buck topology provides efficient power conversion for automotive systems.
- Integrated protection mechanisms include overcurrent, thermal, and undervoltage lockout.
- Adjustable switching frequency allows optimization for size and efficiency trade-offs.
Applications
- 48V vehicle electrical systems
- Dual-voltage hybrid electric vehicle power distribution
- Automotive infotainment and display backlighting supplies
Procurement Notes
Verify the specific suffix 'T' indicates tape and reel packaging configuration. Confirm that the component meets AEC-Q100 qualification requirements for your target automotive environment. Ensure compatibility with the required input voltage range and output current specifications before integration into the final design.
Selection Notes
Select this regulator when designing for 48V automotive architectures requiring high efficiency and compact footprint. Consider the 3.5A continuous current capability and wide input voltage range suitable for harsh automotive environments. Evaluate thermal performance needs based on the TSSOP package and exposed pad thermal dissipation characteristics.
Part Context
This component belongs to the A858x series of high-frequency buck regulators from Allegro MicroSystems. The series targets demanding automotive applications requiring robust power management. Similar models in the family may vary in current rating or input voltage range while maintaining compatible pinouts and control interfaces.
Replacement Considerations
The A8580KLPTR-T is listed as a manufacturer-recommended alternative. Verify functional equivalence regarding current ratings, input voltage ranges, and pin compatibility before substitution. Note that the A8580KLPTR-T status may differ from active production status.
