Description
The EVQ3524-D-4000-00A evaluation board is designed to demonstrate the capabilities of the MPQ3524GDE-4000-AEC1, a configurable-frequency (350kHz to 2.5MHz), synchronous, step-down switching regulator with integrated, internal high-side and low-side MOSFETs (HS-FET and LS-FET, respectively).The MPQ3524GDE-4000-AEC1 provides up to 4A peak of highly efficient output current (IOUT) with peak current mode control. The wide 3.3V to 20V input voltage (VIN) range accommodates a variety of step-down applications in automotive input environments, such as 12V and 5V buses and multi-cell Li-ion batteries. 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 loads to reduce switching and gate driver losses.An open-drain power good (PG) signal indicates whether the output is within 94.5% to 105.5% of its nominal voltage.Frequency foldback prevents inductor current (IL) runaway during start-up. Thermal shutdown provides reliable, fault-tolerant operation. A high duty cycle and low-dropout (LDO) mode are provided for automotive cold-crank conditions.The EVQ3524-D-4000-00A is fully assembled and tested. The MPQ3524GDE-4000-AEC1 is available in a QFN-12 (2mmx3mm) package with wettable flanks, and is AEC-Q100 qualified.
