Allegro MicroSystems Inc. Automotive 2.4 Mhz 3.5 Buck Regulator A8584KLPTR-T

Description
The A8584 is an adjustable frequency, high output current, PWM regulator that integrates a low resistance, high-side, N-channel MOSFET. The A8584 incorporates current-mode control to provide simple compensation, excellent loop stability, and fast transient response. The A8584 utilizes external compensation to accommodate a wide range of power components to optimize transient response without sacrificing stability. The A8584 regulates input voltages from 4.7 to 36 V, down to output voltages as low as 0.8 V, and is able to supply approximately 2.5 A of load current. The A8584 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 A8584 only turns on the lower FET to charge the boot capacitor when needed, not at every PWM cycle. This improves light load efficiency and provides no-load currents low. The sleep mode current of the A8584 control circuitry is less than 3 μA. Protection features include VIN undervoltage lockout (UVLO), pulse-by-pulse overcurrent protection (OCP), hiccup mode short-circuit protection (HIC), and thermal shutdown (TSD). In addition, the A8584 provides adjacent pin short-circuit and short-to-ground protection at every pin to satisfy the most demanding applications. The A8584 device is available in a 16-pin TSSOP package with exposed pad for enhanced thermal dissipation. It is lead (Pb) free, with 100% matte tin leadframe plating.
