It provides up to 4A highly efficient output current (IOUT) with current mode control for fast loop response. The wide 3.3V to 45V input voltage (VIN) range accommodates a variety of step-down applications in automotive input environments. High power conversion efficiency across a wide load range is achieved by scaling down the switching frequency (fSW) under light-load conditions to reduce the switching and gate driver losses. An open-drain power good (PG) signal indicates whether the output is within 95% to 105% of its nominal voltage. High-duty cycle and low-dropout mode are provided for automotive cold crank conditions. The MPQ4314 is available in a QFN-20 (4mmx4mm) package. Applications include automotive infotainment\/clusters, advanced driver assistance systems (ADAS) and industrial power systems. \u003cul\u003e \u003cli\u003e18µA sleep mode quiescent current (IQ), 1.7µA shutdown mode quiescent current, fixed output of 3.3V\u003c\/li\u003e \u003cli\u003eInternal 48mohm high-side MOSFET (HSFET) and 20mohm low-side MOSFET (LSFET)\u003c\/li\u003e \u003cli\u003e350KHz to 1000kHz programmable switching frequency (fSW) for car battery applications\u003c\/li\u003e \u003cli\u003eSynchronize to external clock\u003c\/li\u003e \u003cli\u003eOut-of-phase synchronized clock output\u003c\/li\u003e \u003cli\u003eFrequency spread spectrum for low EMI, thermal shutdown provides reliable, fault-tolerant operation\u003c\/li\u003e \u003cli\u003eSymmetric VIN for low EMI, power good (PG) output, external soft start (SS), 100ns minimum on time\u003c\/li\u003e \u003cli\u003eSelectable advanced asynchronous modulation (AAM) mode or forced continuous conduction mode (FCCM)\u003c\/li\u003e \u003cli\u003eLow-dropout mode, hiccup overcurrent protection (OCP),AEC-Q100 grade 1 qualified\u003c\/li\u003e \u003cli\u003eFrequency foldback helps prevent inductor current runaway during start-up\u003c\/li\u003e \u003c\/ul\u003e Footnotes MPS part numbers ending in \"-P\" and \"-Z\" are the same parts.
