降压型DC/DC转换器,R1245,R1245N001G-TR-FE,R1245N001A/BC/D 降压型DC/DC转换器,R1245,R1245N001G-TR-FE,R1245N001A/BC/D 降压型DC/DC转换器,R1245,R1245N001G-TR-FE,R1245N001A/BC/D 降压型DC/DC转换器,R1245,R1245N001G-TR-FE,R1245N001A/BC/D

R1245N001G-TR-FE是日清纺(NISSHINBO)的一款采用CMOS制造工艺的降压型DC/DC转换器,输入电压范围为4.5V~30V,提供最大1.2A输出电流。用户在光模块测试板上用R1245N001G-TR-FE实现6V转5V,测试中发现实际输出电压偏低,本文将具体分析此问题并给出解决办法。


测试问题:

实际设计要求输入6V,输出5V,在空载和带载下输出均为4.2V左右,并且FB脚电压只有0.67V,低于规格书上描述的0.8V。


问题分析及解决:

1、  检查客户原理图参数和layout,并未发现异常;

2、  由于输入输出电压压差较小,考虑可能是占空比过大导致异常,对标规格书中占空比参数(图1)发现,R1245N001G最大占空比为76%,根据BUCK电路占空比计算公式:D=Vout/Vin得到5/6=0.83>0.76,不满足最大占空比要求;

3、  两种解决办法:

(1)选择R1245N001A/BC/D,最大占空比为92%,可实现低压差设计;

(2)提高输入电压值,用户将直流源设置为12V,DCDC正常输出5V。
