The EVQ4372-V-1001-00A evaluation board is designed to demonstrate the capabilities of the MPQ4372GVE-1001-AEC1, a dual-phase application, synchronous, step-down switching regulator with integrated, low on resistance (R_DS(ON)) high-side and low-side power MOSFETs (HS-FET and LS-FET, respectively). Part of a highly scalable family of parts, the MPQ4372-1001-AEC1 provides up to 11A of output current (I_OUT) and employs Zero-Delay PWM (ZDP^TM) control, an MPS-exclusive technology that delivers extremely fast transient response and reduces the need for costly external capacitors. The evaluation board can provide up to 22A of I_OUT.

The wide 3.3V to 36V input voltage (V_IN) range accommodates a variety of step-down applications in automotive input environments. A 1.8μA shutdown-mode quiescent current (I_Q) 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 (f_SW) under light-load conditions to reduce switching and gate driver losses.

An open-drain power good (PG) signal indicates whether the output is within 94% to 106% of its nominal voltage. Frequency foldback helps prevent inductor current (I_L) runaway during start-up. Thermal shutdown provides reliable, fault-tolerant operation.

A high duty cycle and low-dropout (LDO) mode provide support for automotive cold-crank conditions.

The EVQ4372-V-1001-00A is a fully assembled and tested evaluation board. The MPQ4372GVE-1001-AEC1 is available in a QFN-23 (4mmx5mm) package with wettable flanks, and is available in AEC-Q100 Grade 1.
