Monolithic Power Systems MPQ4323M | Demoboard EVQ4323M-G-00A

Description

The EVQ4323M-G-00A evaluation board is designed to demonstrate the capabilities of the MPQ4323M, 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 MPQ4323M provides 3A of highly efficient output current (IOUT) with peak current control mode. The wide 3.3V to 36V input voltage (VIN) range and 42V load dump toleranceaccommodates a variety of step-down applications in automotive input environments. A 1μA quiescent current (IQ) in shutdown mode allows the device to be used in battery-powered applications.
