——概述：
南芯SC8701是一个同步4开关降压升压控制器，它可以有效地输出电压，无论是高、低或等于输入电压。同时也支持非常宽的输入和输出电压范围，设计南芯100W《SC8701>方案振邦微 ，它可以支持2.7V到36V的输入范围和2V到36V的输出范围。驱动器电压设置为10V，以充分利用外部mosfet实现效率。SC8701同步升降压直流/直流转换器，采用抖动频率、平均电流模式控制架构。能够驱动高达20a的连续负载，具有良好的线路和负载调节能力。设计南芯100W《SC8701>方案振邦微 ，SC8701具有短路和热保护电路，以提高系统的可靠性。内部软启动避免启动时输入涌电流。SC8701需要少数量的外部组件。以及广泛的保护功能，以提高可靠性.Nanxin sc8701 is a synchronous 4-switch step-down and boost controller, which can effectively output voltage, whether high, low or equal to input voltage. It also supports a very wide input and output voltage range, Design the Nanxin 100W sc8701> scheme Zhenbang micro, which can support the input range of 2.7V to 36V and the output range of 2V to 36V. The driver voltage is set to 10V to make full use of the external MOSFET to achieve the highest efficiency. The sc8701 synchronous voltage rise / fall DC / DC converter adopts the jitter frequency and average current mode control architecture. It can drive continuous loads up to 20a, and has good line and load regulation capabilities. Design the Nanxin 100W According to the sc8701> scheme, the sc8701 has a short circuit and thermal protection circuit to improve the reliability of the system. The internal soft start avoids the input of inrush current during startup. The sc8701 requires a minimum number of external components. It also has a wide range of protection functions to improve the reliability
