EVQ4323M-G-00A

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). 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. An open-drain power good signal indicates whether 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 coldcrank conditions.

• Input voltage range 3.3V to 36V, VOUT = 5V, switching frequency is 2.2MHz
• 3A of highly efficient output current (IOUT) with peak current control mode
• 42V load dump tolerance
• 1μA quiescent current in shutdown mode allows the device to be used in battery-powered applications
• Fully assembled and tested
• Available in a QFN12L (3.5mmx3.5mm) package with wettable flanks
• Available in AEC-Q100 grade 1
