Transformer Driver for Isolated RS-485 Interface

General Description The MAX253 is a monolithic oscillator/power-driver, specifically designed to provide isolated power for an isolated RS-485 or RS-232 data interface. It drives a center-tapped transformer primary from a 5V or 3.3V DC power supply. The secondary can be wound to provide any isola

1W原边变压器H桥驱动器，用于隔离电源

MAX253单片振荡器/功率驱动器专门用于为隔离式RS-485或RS-232数据接口提供隔离电源。该器件通过5V或3.3V直流电源驱动中心抽头变压器原边。可以绕制副边线圈以在高达1W的功率水平下提供所需的任何隔离电压。\n\n MAX253包含一个CMOS振荡器，用于驱动一对N沟道电源开关。振荡器以双倍输出频率运行，驱动一个翻转触发器以确保每个开关的占空比为50%。设置了内部延迟以确保在两个开关之间提供先开后合动作。\n\n SD引脚将整个器件置于低功耗关断状态，此时电源开关和振荡器都会禁用。\n\n   • 用于隔离式RS-485/RS-232数据接口应用的简单电源变压器驱动器设计\n• 5V或3.3V单电源\n\n• 低电流关断模式：0.4µA\n\n• 引脚可选频率：350kHz或200kHz\n\n\n\n\n• 8引脚DIP、SO和µMAX®封装只需占用很小的电路板空间;
