目录7.相关产品 产品概述 返回TOP The CXSU63205 is a constant frequency, 6-pin SOT23 current mode step-up converter intended for small,low power applications. The CXSU63205 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 CXSU63205 features automatic shifting to pulse frequency modulation mode at light loads. The CXSU63205 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The CXSU63205 is available in a small 6-pin SOT-23-6 package. CXSU63205是一款固定频率，内部的软启动有很小脉冲电流可延长电池寿命。CXSU63205 1.2MHz转换频率允许用微小和低成本的电容， 电感高度可小于2mm，CXSU63205在轻负载时自动 转成脉冲频率调制模式。CXSU63205有欠压锁定. 限流和热过载保护。 产品特点 返回TOP
