【应用】高压型LDO,应对扫地机器人高压差电压线性转换,最高可达40V
在扫地机器人中,其电源通常来至于内部的4节锂电池,总电压为17.2V左右,电机驱动,主控,传感器等的用电都由这前端的17V电压源供电,大电流部分,可以用DCDC做电压转换,而主控部分,电流比较小,并且对于纹波控制要求高,因此大多采用线性稳压供电,也就是LDO。
常规的LDO都是用的5V转3.3V,而在扫地机器人中,由于前端电压是17V,为了减少纹波的干扰,通常采用LDO直供电的方式,因此就需要一颗支持耐压在17V以上的LDO。
电源应用原理图入下:
图1
封装信息如下:
图2
由于支持的压差比较大,因此对于电源设计,接地铺铜要求较高,以提高散热性能。
电源特性参数如下:
1、输入电压:4.75V~40V;
2、输出电压:1.8V~5.7V;
3、输出精度:<±2%;
4、输出电流:100mA(典型值);
5、高达150mA @ VIN = 12V,VOUT = 5V;
6、PSRR:60dB @ 100Hz;
7、滤除电压:600mV @ IOUT = 100mA;
8、静态电流:4.2μA@ VIN = 12V(典型值);
9、ESDHBM:8KV;
10、推荐电容:10μF。

洺太SUL6001:大电流、低压降LDO,助力高效电源管理
随着应用产品对高质量、大量数据处理的要求和环境条件因素的制约,对供电负载要求越来越大,同时对电源自身带来的干扰影响却要越来越小,并且对损耗也希望越来越低。洺太电子(SUNTEK)推出的SUL6001是一款高性能的低压降线性稳压器(LDO),它支持最大1A的负载电流,同时在输出电压为3.3V的情况下,其压降分别只有85mV@1A和50mV@500mA。
