产品详情资料

与迹线电感串联也会导致显著的输入电压振铃。输入电压步骤如果输入电压低于调节的输出电压,内部MOSFET的体二极管将电流从输出电源传导至输入电源。如果输入电压快速下降,则电感器两端的电压将显著,并可能使电感器饱和。然后,大电流将流过MOSFET体二极管,导致过度的功耗,从而可能损坏零件。如果预计输入电源上会出现快速电压阶跃,请将一个小型硅或肖特基二极管与VIN引脚串联,以防止反向电流和电感器饱和,如图4中的D1所示。二极管的尺寸应适合大于调节输出电压的反向电压,并能承受高于LTC7138大峰值电流的重复电流。图4。防止电流流向输入输入SW电源LTC7138 COUT 7138 F04 CIN VOUT VIN L D1陶瓷电容器和可听噪声更高值、更低成本的陶瓷电容器现在可用于更小的外壳尺寸。其高纹波电流、高电压额定值和低ESR使其成为开关稳压器应用的理想选择。但是,在输入和输出端使用这些电容器时必须小心。当在输入端使用陶瓷电容器时,LTC7138 14 7138f了解更多信息in series with trace inductance can also lead to significant input voltage ringing. Input Voltage Steps If the input voltage falls below the regulated output voltage, the body diode of the internal MOSFET will conduct current from the output supply to the input supply. If the input voltage falls rapidly, the voltage across the inductor will be significant and may saturate the inductor. A large current will then flow through the MOSFET body diode, resulting in excessive power dissipation that may damage the part. If rapid voltage steps are expected on the input supply, put a small silicon or Schottky diode in series with the VIN pin to prevent reverse current and inductor saturation, shown below as D1 in Figure 4. The diode should be sized for a reverse voltage of greater than the regulated output voltage, and to withstand repetitive currents higher than the maximum peak current of the LTC7138. Figure 4.

Their high ripple current, high voltage rating, and low ESR make them ideal for switching regulator applications. However, care must be taken when these capacitors are used at the input and output.
