目录7.相关产品 产品概述 返回TOP CXSU63146系列是电流和电压多重反馈升压型DC/DC控制器。电流感应电阻, 时钟频率和运算放大器反馈增益都可以在外部调节。该系列可提供稳定的输出电流高达1.5A,并且输出电压可以在2.5V-16.0V范围内(内部设定)以100mV间隔选择(精度±2.5%)。此外,还有包含0.9V内部参考电压源, 可通过外部器件自由设定输出电压的型号可供选择(FB type)。开关频率可以在100~600kHz范围内外部调节,因此可以选择最适合您特定应用的频率。另外,可通过电流感应电阻设定驱动三极管的限流,并且软启动时间也可用外接电阻, 电容来调节。当关断后,(CE=“L”), 消耗电流可减小到0.5μA或更小。The CXSU63146 series are step-up multiple current and voltage feedback DC/DC controller ICs. Current sense, clock frequencies and amp feedback gain can all be externally regulated. A stable power supply is possible with output currents of up to 1.5A. With output voltage fixed internally, VOUT is selectable in 0.1V increments within a 2.5V ~ 16.0V range (±2.5%). For output voltages outside this range, we recommend the FB version, which has a 0.9V internal reference voltage. Using this version, the required output voltage can be set using 2 external resistors. Switching frequency can also be set externally within a range of 100 ~ 600 kHz and therefore a frequency suited to your particular application can be selected. With the current sense function, peak currents (which flow through the driver transistor and the coil) can be controlled. Soft-start time can be adjusted using external resistor and capacitor. During shutdown (CE pin=L), consumption current can be reduced to as little as 0.5μA (TYP.) or less 产品特点 返回TOP 应用范围 返回TOP ●E-book Reader / Electronic dictionaries ●Portable game consoles ●Mobile devices / terminals ●Digital still cameras / Camcorders ●Smart phones / Mobile phones ●Note PCs / Tablet PCs 技术规格书(产品PDF) 返回TOP 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!
