ADuM640x with 1 cell LiPo supply

hi there,

i'm developing a medical device (powered by 1 LiPo cell) and therefore have to isolate the sensors from the digital part (connected through SPI), so the ADuM6401 seems perfect to me.

does anyone have an elegant solution in mind to connect the LiPo to the ADuM's DC/DC converter operating at 3V3 except using a buck/boost converter?

 

thanks in advance.

un saludo,

joe
