3W原边变压器H桥驱动器，用于隔离电源

MAX256是一款用于隔离电源电路的集成原边控制器和H桥驱动器。该器件含有板上振荡器、保护电路以及内部FET驱动器，可为变压器的主绕组提供高达3W功率。MAX256可采用内部可编程振荡器工作模式，或由外部时钟驱动以改善EMI性能。无论使用哪个时钟源，内部触发器都可确保占空比固定为50%，从而防止直流电流流入变压器。\n\n MAX256采用+5V或+3.3V单电源供电，并具有欠压锁定功能，以实现受控的启动过程。该器件通过先开后合的切换模式防止H桥MOSFET交叉导通。在高温情况下，热关断电路还提供额外的保护功能避免器件损坏。\n\n MAX256采用8引脚、热增强型 • 可为隔离电源中的变压器提供高达3W的功率\n• +5V或+3.3V单电源供电\n• 可通过电阻编程设置内部振荡器模式 \n• 带看门狗的外部时钟模式\n• 禁止模式\n• 欠压锁定\n• 热关断;
