一,产品概述(General Description) step-down switching regulator, capable of delivering up to 0.7A of output current. With a fixed switching frequency of 660KHz, 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.CXSD6141 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 CXSD6141 must be used to minimize thermal dissipation. CXSD6141 is available SOT23-6 Packages. 二.产品特点(Features) ·Wide Input Operating Range from 4V to 38V ·Standoff Input Voltage: 42V ·High Efficiency at 12V In 5V Out: Up to 92%: ·High Efficiency PFM mode at light load ·Capable of Delivering 0.7A ·No External Compensation Needed ·Current Mode control ·Logic Control Shutdown ·Thermal shutdown and UVLO ·Available in SOT23-6 Package 三,应用范围 (Applications) Smart Meters Industrial Applications Automotive Applications 四.技术规格书下载(产品PDF) 需要详细的PDF规格书请扫一扫微信联系我们,还可以获得免费样品以及技术支持!
