Allegro MicroSystems Inc. Automotive, Dual Synchronous, Low Voltage Buck A8651KLPTR-T-1

Description
The A8651 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 A8651 incorporates current-mode control to provide simple compensation, excellent loop stability, and fast transient response. The A8651 utilizes external compensation to accommodate a wide range of power components to optimize transient response without sacrificing stability. The A8651 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 up to 2 A of load current per regulator. The A8651 features include an externally adjustable and synchronizable switching frequency, an externally-set soft start time to minimize inrush currents, independent EN inputs, and independent NPOR outputs with either 7.5 ms (A8651) or 120 μs (A8651-1) delay. The sleep mode current of the A8651 control circuitry is less than 5 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 A8651 provides open-circuit, adjacent pin short-circuit, and short-to-ground protection at every pin to satisfy the most demanding automotive applications. The A8651 device is available in a 20-pin TSSOP package with exposed thermal pad for enhanced thermal dissipation (suffix LP). It is lead (Pb) free, with 100% matte tin leadframe plating.
