MPQ4323GDE-AEC1规格书详情
DESCRIPTION
The MPQ4323 is a frequency-configurable (350kHz to 2.5MHz), synchronous, step-down switching regulator with integrated internal highside and low-side power MOSFETs. The device provides 3A of highly efficient output current with peak current mode control.
The wide 3.3V to 36V input voltage range and 42V load dump tolerance accommodates a variety of step-down applications in automotive input environments. A 1μA shutdown current (ISD) 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 driving losses.
An open drain power good 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 MPQ4323 is available in QFN-12 (2mmx3mm) and QFN-12 (3mmx4mm) packages.
