Isolated Transformer Driver for PCMCIA Applications

General Description The MAX845 provides an isolated power supply small enough to fit in thin PCMCIA cards and space-sensitive applications. It drives a low-profile center-tapped transformer primary from a 5V or 3.3V DC power supply. The secondary can be wound to provide any isolated positive or

隔离型、变压器驱动器，适用于PCMCIA设计

MAX845提供足够小的隔离电源，适合薄型PCMCIA卡和对空间敏感的应用。它通过5V或3.3V直流电源驱动薄型中心抽头变压器原边。可通过副边绕组在高达750mW的功率下提供任何隔离的正电压或负电压。\n\n MAX845由一个振荡器和一个触发器组成。触发器产生两个占空比为50%的方波，它们在振荡器频率的一半（450kHz，最小值）处互补。这两个信号用于驱动以地为参考的N沟道电源开关。内部电路确保在两个开关之间提供先开后合动作。\n\n 低功耗关断模式会禁用开关和振荡器，从而降低功耗。提供了评估套件(MAX845EVKIT-MM)以评估薄型5V 40mA和5V 10 • 用于超薄5V-µs变压器的变压器驱动器\n\n• 适合PCMCIA应用的隔离式DC-DC电源\n\n• 450kHz最小开关频率\n\n• 超低输入电源电流纹波\n\n• +5V或+3.3V单电源\n\n• 低功耗关断模式：5µW\n\n• 8引脚SO和µMAX封装\n\n• 低输出纹波支持使用微型输出电容;
