LTC3727死区时间不够，导致炸管 0
Answered

产品采用2颗LTC3727并联输出形式，出现很高概率NMOS炸管的问题。经测量上下NMOS的驱动波形如下图，黄色是TG，蓝色是BG，如图1，有上下管同时导通的风险，请帮忙分析和解决。

LTC2500-32 SDOA无输出 0
Answered

我现在在配置LTC2500-32 A通道输出，波形如上图，硬件原理图如上图。现在我 RDLA拉低，RDLB拉高，PRE接REF，启用默认32位滤波输出，SDI接高电平3.3V，数字滤波器将配置为DGC和DGE均关闭的平均滤波器。但是SDOA并没有数据在输出。

LTC3765和LTC3766采用独立供电时，仿真发现LTC3765供电电压稍高时，控制权移交给LTC3766后，LTC3765无法正常检测占空比脉冲信号，导致重启 0
Answered

LTC3765和LTC3766均采用外部直接供电，LTC3765供电端串联有二极管防止电源电流倒灌。仿真时，LTC3766采用9V供电，LTC3765采用13V供电时，发现LTC无法识别脉冲变压器发送来的占空比信号，导致故障重启。分析原因似乎是由于LTC3765供电电压大于整流后的电压太多导致无法识别占空比信号。想问一下ADI的相关人员，实际器件是这样的么，如果是这样的话，在设计电路时，脉冲变压器匝数比，LTC3766供电电压，LTC3765供电电压是否存在一个限制关系，在电路设计时，为了避免由于此原因造成的故障...

四路级联LT8292时，电流不能平均分配的原因？ 0
Answered

测试环境（升压）：输入31-43V，输出46.5V，四个芯片单独可以达到20A，但是四个级联时，电流不能平均分配,如下：备注1：虽然电流不能平均，但是所有的波形很固定　 U1 U3 U2 U4 28.2A 8.7A 8.7A 5.4A 5.4A 41.4A 12.7A 12.7A 7.98A 7.98A 55.4A 17.3A 17.3A 10.7A 10.7A

LT8491EUKJ上电没有输出 +1
Not Answered

1、加电50V后测量LDO33有电压3.3V输出，上电输入电流0.11A，BGT1等开关引脚没有PWM输出； 2、是否需要通过 I2C 来控制内部 switch 使能，如果不用 I2C 控制内部 Switch 使能是不是也可以使 PWM 输出；
