The A8585KLKTR-T from Allegro MicroSystems is a high-current buck switching regulator designed for automotive audio and infotainment systems. It offers a fixed 5V output with an accuracy of ±1.0% and can deliver up to 2.0A of output current.
This regulator operates from an input voltage range of 4V to 35V and features a programmable switching frequency adjustable from 300kHz to 550kHz. It includes features like current mode control for stability and fast transient response, and a Low IQ mode utilizing pulse frequency modulation (PFM) to minimize current draw. The device also supports external synchronization and has a fixed soft-start time of 5ms.
Designed for automotive applications, the A8585KLKTR-T is AEC-Q100 qualified and can withstand surge inputs up to 40V for load dump conditions. It operates down to 3.4V typical for idle stop scenarios. The regulator is housed in a 10-LSOP package with an exposed thermal pad and is suitable for surface mount applications.
Key electrical characteristics include a 2A output current capability, 5V fixed output voltage, and a switching frequency range of 300kHz to 550kHz. The device integrates a 110 mΩ high-side MOSFET. Its Low IQ mode draws less than 33 µA from a 12V input while supplying 5.0V/40 µA, making it efficient for various power supply requirements.
