MPQ4320規(guī)格書詳情
DESCRIPTION
The MPQ4320 is a configurable-frequency
(350kHz to 1.8MHz), synchronous, step-down
switching converter with integrated internal highside and low-side power MOSFETs (HS-FET
and LS-FET, respectively). The device provides
up to 0.5A 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 accommodates a
variety of step-down applications in automotive
input environments. A 1μA shutdown current
(ISD) allows the device to be used in batterypowered applications.
High power conversion efficiency across a wide
load range is achieved by scaling down the
switching frequency (fSW) under light-load
conditions to reduce switching and gate driver
losses.
An open-drain power good (PG) signal indicates
whether the output is within 94.5% to 105.5% of
its nominal voltage.
Frequency foldback helps prevent inductor
current (IL) runaway during start-up. Thermal
shutdown provides reliable, fault-tolerant
operation. High duty cycle and low-dropout (LOD)
mode are provided for automotive cold-crank
conditions.
The MPQ4320 is available in a QFN-12
(2mmx3mm) package with wettable flanks or a
QFN-12 (3mmx4mm) package with wettable
flanks, and is AEC-Q100 qualified.
