The MT3608 is a constant frequency, 6-pin SOT23 current mode step-up converter intended for small, low power applications. The MT3608 switches at 1.2MHz and allows the use of tiny, low cost capacitors and inductors 2mm or less in height. Internal soft-start results in small inrush current and extends battery life.

    The MT3608 features automatic shifting to pulse frequency modulation mode at light loads. The MT3608 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The MT3608 is available in a small 6-pin SOT-23 package.

    MT3608是一种恒定频率的6引脚SOT23电流模式升压转换器，低功耗应用。MT3608在1.2MHz，并允许使用微小、低成本电容器和电感器的高度不超过2mm。内部软启动导致较小的涌入电流延长电池寿命。

    MT3608具有自动切换到脉冲的功能轻负载时的频率调制模式。这个MT3608包括欠压锁定、电流限制和热过载保护，以防止输出过载时的损坏。这个MT3608可在小型封装SOT-23-6中使用。
