EVQ4326-R-00A

The EVQ4326-R-00A evaluation board is designed to demonstrate the capabilities of the MPQ4326-AEC1, a synchronous, step-down switching converter with a configurable frequency and integrated internal high-side MOSFET (HS-FET) and low-side MOSFET (LS-FET). The MPQ4326-AEC1 provides up to 6A of highly efficient output current (I_OUT) with current mode control for fast loop response.

The wide 3.3V to 36V input voltage (V_IN) range with 42V load dump support accommodates a variety of step-down applications in automotive input environments. A 1μA shutdown mode quiescent current allows the device to be used in battery-powered applications.

High power conversion efficiency across the wide load range is achieved by scaling down the switching frequency (f_SW) under light-load conditions to reduce the switching and gate driving losses.

An open-drain power good (PG) signal indicates whether the output is within 94.5% to 105.5% of its nominal voltage.

Thermal shutdown provides reliable, fault-tolerant operation. A high duty cycle and low-dropout mode are provided for automotive cold-crank conditions.

The EVQ4326-R-00A is a fully assembled and tested evaluation board. The MPQ4326-AEC1 is available in a QFN-14 (4mmx4mm) package with wettable flanks. It is available in AEC-Q100 Grade 1.
