LTC3859 - pcb reference design


Could you share with pcb reference design please?

As I do not found eval board for this IC I design pcb. Unfortunately looks like I did something wrong because load on Vout2 makes channel Vout3 blow up (if also under load).

So only Vout1 and Vout2 or Vout1 and Vout3 can work in same time.

I used your circuit Figure 15. High Efficiency 1.2V/3.3V Step-Down Converter with 10.5V SEPIC Converter.

Thanks SLA
