   产品概述 返回TOPsfe嘉泰姆

        CXSD62604是一种宽输入范围,高效率,同步降压开关稳压器,能够提供高达0.4A的输出电流。采用固定开关频率的700Khz。外围器件少。CXSD62604还采用专有控制方案,在光负载期间将设备切换到省电模式,从而扩展高效操作的范围。OVP功能可以承受高达42V的输入电压,使其成为智能仪表和汽车应用等工业应用的理想解决方案。CXSD62604采用SOT23-6封装The CXSD62604 is a wide input range, high-efficiency, synchronous step-down switching regulator, capable of delivering up to 0.4A of output current. With a fixed switching frequency of 700KHz, 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.CXSD62604 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 9Vand 24V. Including coldcrank and double battery jump-starts, the minimum input voltage may be as low as 5V 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 CXSD62604 must be used to minimize thermal dissipation. CXSD62604 is available SOT23-6 Packages.
