EVQ4316-R-01A

EVQ4316-R-01A is an evaluation board designed to demonstrate the capabilities of the MPQ4316, a synchronous, step-down switching regulator with a configurable frequency, as well as an integrated, internal high-side MOSFET and low-side MOSFET. It can provide up to 6A of highly efficient output current, with current mode control for fast loop response. The 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 the switching frequency under light-load conditions to reduce the switching and gate driver losses. Frequency foldback prevents inductor current runaway during start-up. Thermal shutdown provides reliable, fault-tolerant operation. The MPQ4316 is available in a QFN-20 (4mmx4mm) package and AEC-Q100 Grade 1 qualified.
