EVQ4313-R-01A evaluation board is designed to demonstrate the capabilities of the MPQ4313, a synchronous, step-down switching regulator with a configurable frequency and an integrated, internal high-side MOSFET (HSFET) and low-side MOSFET (LS-FET). It provides up to 3A of highly efficient output current (IOUT), with current mode control for fast loop response. Wide 3.3V to 45V input voltage range accommodates a variety of step-down applications in automotive input environments. A 1.7µA quiescent current 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 switching frequency (fSW) under light-load conditions to reduce switching and gate driver losses. Frequency foldback helps prevent inductor current runaway during start-up. Thermal shutdown provides reliable, fault-tolerant operation. High-duty cycle and low-dropout mode are provided for automotive cold crank conditions.
