产品概述 返回TOPv1f嘉泰姆
The CXSD61057 is a wide input range, high-efficiency, and high
frequency DC-to-DC step-down switching regulator,
capable of delivering up to 1.5A of output current. With a
fixed switching frequency of 650KHz, this current mode
PWM controlled converter allows the use of small external
components, such as ceramic input and output caps, as
well as small inductors.CXSD61057 also employs a proprietary
control scheme that switches the device into a power save
mode during light load, thereby extending the range of high
efficiency operation. An OVP function protects the IC itself
and its downstream system against input voltage surges.
With this OVP function, the IC can stand off input voltage as
high as 42V, making it an ideal solution for industrial
applications such as smart meters as well as automotive
applications.
In automotive systems, power comes from the battery, with
its voltage typically between 9V and 24V. Including cold
crank and double battery jump-starts, the minimum input
voltage may be as low as 4V and the maximum up to 36V,
with even higher transient voltages. With these high input
voltages, linear regulators cannot be used for high supply
currents without overheating the regulator. Instead, high
efficiency switching regulators such as CXSD61057 must be
used to minimize thermal dissipation.
CXSD61057 is available SOT23-6 Packages
