Overview
The A8583KLPTR-T is a high-frequency synchronous buck regulator from Allegro MicroSystems, designed for automotive applications. It operates with an input voltage range of 4.7V to 36V and delivers up to 3.5A output current. The device features adjustable output voltage starting from 0.8V and supports switching frequencies between 250kHz and 2.45MHz. Packaged in a 16-lead TSSOP with exposed pad, it functions within a temperature range of -40°C to 125°C.
Feature Summary
- Integrated synchronous rectification for improved efficiency
- Wide input voltage capability suitable for automotive loads
- Adjustable switching frequency for EMI optimization
- Built-in thermal protection and fault management
Applications
- Automotive infotainment systems
- ADAS sensor power supplies
- Body control modules
- Telematics units
Procurement Notes
Verify the specific suffix 'T' indicates tape and reel packaging configuration. Confirm RoHS compliance status through official datasheets. Check moisture sensitivity level (MSL) requirements for storage and handling. Ensure the supplier provides valid traceability documentation for automotive-grade components.
Selection Notes
Select this component when a 3.5A buck converter is required for 12V or 24V automotive systems. Consider the wide input range if operating near battery terminals. Evaluate the thermal performance in the 16-TSSOP package against board layout constraints. Compare switching frequency options against electromagnetic interference requirements.
Part Context
This part belongs to the A8583 series of high-performance buck regulators. It shares the same package and pinout family as other automotive PMICs from Allegro. The series focuses on robust power delivery in harsh environments. It complements fixed-voltage variants within the broader product line.
Replacement Considerations
Check for direct pin-compatible upgrades within the A8583 series. Verify if higher current variants like the A8589 are suitable for future-proofing designs. Ensure any substitute maintains the same automotive qualification standards.
