Allegro MicroSystems Inc. Automotive Wide Input Voltage 2A Buck Reg A8585KLKTR-T-2

Description
The A8585 family is designed to provide the power supply requirements of next generation car audio and infotainment systems. The A8585 family provides all the control and protection circuitry to produce a high current regulator with ±1% output voltage accuracy. In PWM mode, the A8585 family employs current mode control to provide simple compensation, excellent stability, and fast transient response. In Low IQ mode, the A8585 family employs pulse frequency modulation (PFM) to draw less than 33 μA from 12 VIN while supplying 5 V/40 μA. When operational, the A8585 family operates down to at least 3.6 VIN (VIN falling). The selectable Sleep mode feature allows for very low standby current. Features of the A8585 family include a programmable PWM switching frequency. The regulator switching frequency can be synchronized to an external clock. The A8585 has external compensation to optimize stability and transient response for a wide range of external components and applications. The A8585 has a fixed soft start time of 5 ms. Extensive protection features of the A8585 include pulse-by-pulse current limit, hiccup mode short circuit protection, open/short asynchronous diode protection, BOOT open/short voltage protection, VIN undervoltage lockout, and thermal shutdown. The A8585 is supplied in a 10-pin SOIC package (suffix LK) with exposed power pad. It is lead (Pb) free, with 100% matte-tin leadframe plating.
