Allegro MicroSystems Inc. Low Vin Automotive 2A Sr Buck Regulator A8650KLYTR-T

Description
The A8650 is an adjustable frequency, high output current, PWM regulator that integrates a high-side, P-channel MOSFET and a low-side, N-channel MOSFET. The A8650 incorporates current-mode control to provide simple compensation, excellent loop stability, and fast transient response. The A8650 utilizes external compensation to accommodate a wide range of power components to optimize transient response without sacrificing stability. The A8650 regulates input voltages from 2.5 to 5.5 V, down to output voltages as low as 0.8 V, and is able to supply at least 2.0 A of load current. A8650 features include an externally adjustable switching frequency, an externally set soft start time to minimize inrush currents, an EN/SYNC input to either enable VOUT and/or synchronize the PWM switching frequency, and a Power OK (POK) output to indicate when VOUT is within regulation. The sleep mode current of the A8650 control circuitry is less than 3 μA. Protection features include VIN undervoltage lockout (UVLO), cycle-by-cycle overcurrent protection (OCP), hiccup mode short circuit protection (HIC), overvoltage protection (OVP), and thermal shutdown (TSD). In addition, the A8650 provides open circuit, adjacent pin short circuit, and short to ground protection at every pin to satisfy the most demanding automotive applications. The A8650 is available in both 10-pin MSOP and DFN packages with an exposed pad for enhanced thermal dissipation. It is lead (Pb) free, with 100% matte tin leadframe plating.
