Ideal for applications where space is limited, it switches at 1.2MHz,allowing the use of tiny, low cost and low profile external components. Its internal 2A, 100mΩ NMOS switch provides high efficiency even at heavy load, while the constant frequency,current mode architecture results in low, predictable output noise that is easy to filter. Internal frequency compensation is designed to accommodate ceramic output capacitors, further reducing noise. The device features very low shutdown current of 0.5uA. The CXSU63118 is available in the 6-lead SOT-23 package. 二.产品特点 ● 集成2A 100mΩ MOSFET ● 1.2MHZ固定开关频率 ● 内部集成软启动 ● 支持低至1.6V输入电压范围 ● 3.3V入5V出,可以输出800mA ● 3V入3.3V出,可以输出800mA ● 超小型SOT23-6封装 ● 无铅封装,符合ROHS标准 •Internal 2A MOSFET Switch •1.2MHZ Switching Frequency •Integrated Soft-Start •Low 1.6V Vin Operation •Low ()dsonRSwitch :100mΩat 5V Output •Delivers 5V at 800mA from a 3.3V input •Delivers 3V at 800mA from a 2.5V input •Uses Small.Low Profile External Components •Low profile(1mm):SOT-23(Thin SOT)package 三.应用范围 ● 白光LED驱动供电 ● 3.3V或5V供电 ● 备用电源转换 •White LED Driver Supply •Local 3.3V or 5V supply •Battery Back-up 四.技术规格书(产品PDF) 需要详细的PDF规格书请扫一扫微信联系我们,还可以获得免费样品以及技术支持!
