MPQ4323C
DESCRIPTION
The MPQ4323C is a configurable-frequency (350k Hz 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 (IOUT) with peak current mode control.
The wide 3.3V to 36V input voltage (VIN) range and 42V load dump tolerance acmodates a variety of step-down applications in automotive input environments. A 1μA shutdown mode quiescent current allows use in battery-powered applications.
An open-drain power good (PG) 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 the automotive cold-crank condition.
The MPQ4323C is available in QFN-12 (2mmx3mm), QFN-12 (3mmx4mm), and QFN14 (2.5mmx3.5mm) packages.
