     CXSU63187是一个高效，固定开关频率，PWM控制的DC/DC升压控制器。它为单芯锂电池升压到5V输出提供一个简便易用的电源解决方案。其内置补偿电路及保护电路，以减少外围组件。CXSU63187高达1.2MHz的开关频率可使电感和输出电容小型化，从而节约PCB面积以适应电池供电的应用系统。CXSU63187内置了过温保护、输出短路保护及soft start电路。CXSU63187采用符合RoHS规范及Pb-Free的小尺寸SOT23-5封装。The CXSU63187 is a compact, high efficiency, fixed frequency pulse-width-modulation (PWM) controller. It provides an easy-to-use power supply solution for the application from one Li-ion battery to 5V output. All compensation and protection circuitry are integrated to minimize external components. The 1.2MHz high switching frequency allows smaller inductor and output capacitor, making the CXSU63187 ideally suited for small battery-powered applications and saves PCB space. The CXSU63187 contains thermal shutdown function and output short protection circuit. Built-in soft-start circuitry prevents excessive inrush current during start-up. The CXSU63187is available in a Pb-free, thin-SOT23-5 package.
