Hi,

Is a few TPS61197 can be parallelized ?

I need a 70 to 130V voltage output for 1.3A led current. Is a Buck exists for this kind of output (with a 150-200Vdc input) ?

Hi Thibault,
TPS61197 cannot be paralleized. You could have a try of TPS61196, and connect 6 outputs together to generate higher output current. TPS61196 support 200mA/channel of continous current.
