目录7.相关产品 产品概述 返回TOP CXSU63155系列是1MHz,PWM控制的升压型DC/DC转换器,可使用陶瓷电容。通过内置2.0Ω开关管 ,CXSU63155系列可通过外接一个电感,一个二级管,一个电容和一个电阻就可以轻易获得一个升压电路。由1.0V(±2.0%)参考电压和分压电阻可得到最高19.5V的输出电压(最大Lx工作电压:20V),该系列可用于通用型高电压电源,LCD面板和有机EL显示屏电源。开关频率高达1.0MHz,可使用片式电感和超小的陶瓷电容,因而能减小电路板的面积和厚度。该系列具有限流功能(400mA(TYP.):VDD=3.6V),能够限制流过内置开关管的峰值电流。可通过外置电阻和电容调节软启动时间。待机功能能使输出关断(CE’L’),这个时候,芯片的消耗电流将小于1.0μA。The CXSU63155D10A series is 1MHz, PWM controlled step-up DC/DC converter, designed to allow the use of ceramic capacitors. With a built-in 2.0Ω switching transistor, the CXSU63155D10A series can easily provide a step-up operation by using only a coil, a diode, a capacitor, and a resistor, connected externally. Since output voltage up to 19.5V (Maximum Lx operating voltage: 20V) can be derived with reference voltage supply of 1.0V (±2.0%) and external components, the series can easily supply high voltage for various general-purpose power supplies, LCD panels and organic EL displays. With a high switching frequency of 1.0MHz, a low profile and small board area solution can be achieved using a chip coil and an ultra small ceramic output capacitor. With the current limit function (400mA (TYP.): VDD=3.6V), a peak current, which flows through built-in driver transistors can be limited. Soft-start time can be adjusted by external resistors and capacitors. The stand-by function enables the output to be turned off (CE ’L’), that is, the supply current will be less than 1.0μA. 产品特点 返回TOP
