MPQ4315GRE-AEC1-P

MPQ4315 is a synchronous step-down switching converter with a configurable frequency and integrated internal high-side MOSFET (HS-FET) and low-side MOSFET (LSFET). It provides up to 5A of highly efficient output with current mode control for fast loop response. The wide 3.3V to 45V input range accommodates a variety of step-down applications in automotive input environments. Its low 1.7μA shutdown mode quiescent current makes the MPQ4315 ideal for use in battery powered applications. An open-drain power good signal indicates whether the output is within 93% to 106% of its nominal voltage. Thermal shutdown provides reliable, fault-tolerant operation. High-duty cycle and low-dropout mode are provided for the automotive cold crank conditions. It is available in a QFN-20 (4x4mm) wettable flank package and is AEC-Q100 Grade 1 qualified. Applications includes automotive infotainment, automotive clusters, advanced driver assistance systems and industrial power systems.
