EVQ4323-D-00A 36V, 3A, Low Quiescent Current, Synchronous Step-Down Converter Evaluation Board, AEC-Q100 Qualified
The EVQ4323-D-00A is an evaluation board for the MPQ4323, a configurable-frequency (350kHz to 2.5MHz), synchronous, step-down switching regulator with integrated internal high-side MOSFETs (HS-FETs) and low-side MOSFETs (LS-FETs).
The MPQ4323 provides 3A of highly efficient output current (IOUT) with peak current mode control. The wide 3.3V to 36V input voltage (VIN) range and 42V load dump tolerance accommodates a variety of step-down applications in automotive input environments.
A 1μA shutdown mode quiescent current (IQ) 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 the switching and gate driving losses. An open-drain power good (PG) signal indicates that the output is within 94.5% to 105.5% of its nominal voltage. Frequency foldback helps prevent inductor current runaway during start-up. Thermal shutdown provides reliable, fault-tolerant operation. A high duty cycle and low-dropout mode are provided for automotive cold-crank conditions.
The EVQ4323-D-00A is fully assembled and tested. The MPQ4323 is available in a QFN-12 (2mmx3mm) package with wettable flanks.
