主电源是24v,用两个1k电阻分压成12v给LTC3245供电,LTC3245会把分压出来电压拉低,是因为分压出来的电流不够吗
1. Io of LTC3245 go up to 250mA, should be sufficient to drive two DRVCC of LTM4613
2. It should be ok to power up LTC6908 from LTC3245. The LTC3245 datasheet shows Vout ripple around 20-30mV for low noise mode. You can add more cap at V+ pin of LTC6908…
