MP4571規(guī)格書詳情
DESCRIPTION
The MP4571 is a fully integrated, fixedfrequency,
synchronous step-down converter. It
can achieve up to 1A of continuous output
current with peak current control for excellent
transient response.
The wide 4.5V to 60V input voltage range
accommodates a variety of step-down
applications in an automotive input environment.
A 2μA shutdown mode quiescent current makes
it ideal for battery-powered applications.
The MP4571 integrates internal high-side and
low-side power MOSFETs for high efficiency
without an external Schottky diode, and is
available in a 12-pin QFN package.
The MP4571 employs advanced asynchronous
modulation (AAM), which achieves high efficiency
during light load by scaling down the frequency to
reduce the switching and gate driver losses.
The MP4571 offers standard features including
built-in soft start, enable control, and a power
good indicator. High duty cycle and low-dropout
mode are provided for automotive cold crank
conditions. In addition, the chip provides overcurrent
protection with valley current detection,
which helps prevent current runaway. It also has
hiccup short-circuit protection (SCP), input undervoltage
lockout (UVLO), and auto-recovery
thermal protection.
With internal compensation, the MP4571 offers
a very compact solution with a minimum number
of readily available, standard external
components. It is available in a QFN-12
(2.5mmx3mm) package.
