MT3608 Description/概述:
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是一種恒定頻率的6引腳SOT23電流模式升壓轉(zhuǎn)換器,低功耗應(yīng)用。MT3608在1.2MHz,并允許使用微小、低成本電容器和電感器的高度不超過2mm。內(nèi)部軟啟動(dòng)導(dǎo)致較小的涌入電流延長(zhǎng)電池壽命。
MT3608具有自動(dòng)切換到脈沖的功能輕負(fù)載時(shí)的頻率調(diào)制模式。這個(gè)MT3608包括欠壓鎖定、電流限制和熱過載保護(hù),以防止輸出過載時(shí)的損壞。這個(gè)MT3608可在小型封裝SOT-23-6中使用。
