MONOLITHIC POWER SYSTEMS (MPS) MPQ4316AGRE-AEC1-P DC-DC Synchronous Buck Regulator, Adjustable, 3.3V to 45V in, 0.815V to42.75V/6A out, WFQFN-20

MPQ4316A is a configurable-frequency, synchronous, step-down switching converter with an integrated, internal high-side MOSFET (HS-FET) and low-side MOSFET (LS-FET). The device provides up to 6A of 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. A low 1.7μA quiescent current (IQ) in shutdown mode allows the 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) under light-load conditions to reduce switching and gate driver losses. Thermal shutdown provides reliable, fault-tolerant operation. A high duty cycle and low-dropout mode are provided for automotive cold-crank conditions. Applications include automotive infotainment, automotive clusters, ADAS, industrial power systems.
