MONOLITHIC POWER SYSTEMS (MPS) MPQ4326MGRE-AEC1-P DC-DC Switching Synchronous Buck Regulator, Adjustable, 3.3 to 36 V In, 0.8 to 34.2 V/6A Out, QFN-14

MPQ4326MGRE-AEC1-P is a configurable-frequency (200KHz to 2.5MHz), synchronous, step-down switching regulator with integrated internal high side and low-side power MOSFETs (HS-FET and LS-FET, respectively). It features integrated input capacitors to optimize EMI performance and can provide up to 6A of highly efficient output current (IOUT) with peak current mode control. The MPQ4326M can maintain a regulated output voltage (VOUT) across a wide input voltage (VIN) range up to 36V. Over-voltage protection (OVP) allows it to survive load dumps up to 42V. A 1?A shutdown mode quiescent current (IQ) allows this device to be used in battery-powered applications. High power conversion efficiency across a wide load range is achieved by scaling down the switching frequency (fSW) at light loads to reduce switching and gate driver losses. Application includes automotive infotainment, automotive clusters, advanced driver-assistance systems, industrial power systems.
