Hi:

I need to power an Arduino DUE from a 3.6V Li-ion battery. Unfortunately Arduino DUE needs at least 7V. What type of boost converter could i use ?

thanks

what is the output current in your application? We have TpS61085, TPS61087, TPS61088/89, it depend on your output power rating.

The integarted boost converter TPS61088 can output 12V/2A at Vin=3.3V condition. but it can't support 12V/3A. this is the interated boost converter with highest output power.

Sugggest you use a boost controller, like LM3478/81.

is it ok to use TPS61089x ?

TPS61089 only can output 12V/1.2A at Vin=3.3V condition. So it doesn't fit!
