产品概述 返回TOPX2U嘉泰姆
CXSU63181是一款高效固定频率同步升压转换器,其500KHz的工作频率能在较大负载范围内提供简洁的应用电路。CXSU63181工作在500KHz频率,并内置两个低电阻值功率管,集成了补偿网络和多种保护功能,使得其应用电路非常简洁,所占PCB面积小,适合小功率电池应用场合。另外,在关断模式下,输入与输出之间完全断开,能极大的提高电池的使用时间。CXSU63181内置过温保护和逐周期电流极限,用于实现输出短路保护。同时,内置软启动电路能压制启动时的电流过冲。CXSU63181采用无铅的SOT23-5封装。The CXSU63181 is a compact, high efficiency, fixed frequency,
synchronous step-up converter. The 500KHz switching
frequency allows for smaller external components producing
a compact solution for a wide range of load currents.
High efficiency is accomplished by integrating the low
resistance N-Channel Boost switch and synchronous
P-Channel switch. All compensation and protection circuitry
are integrated to minimize external components. The
500KHz high switching frequency allows smaller inductor
and output capacitor, making the CXSU63181 ideally suited for
small battery-powered applications and saves PCB space.
During shutdown, true load disconnect between battery and
load prevent current flow from VIN to VOUT, as well as
reverse flow from VOUT to VIN, which will extend the battery
life greatly.
The CXSU63181 contains thermal shutdown function and
cycle-by-cycle current limit to protect the device in the event
of an output short-circuit condition. Built-in soft-start
circuitry prevents excessive inrush current during start-up.
The CXSU63181 is available in a Pb-free, SOT23-5 package.
