Hi Team,
I am promoting OPA564 in middle-voltage Power line communication market. And I noted that this part have 20Vpp at 1.5A output capability shown in datasheet.
But as my lab testing, OPA564 can easily went into thermal shutdown even at around 20Vpp@300mA condition, scopeshot shown as below. I know we need a very good heat dissipation PCB design to achieve 20Vpp@1.5A output.
So could you help on below support needed:
Support needed:
[1] do we have PCB reference design if we want to use single OPA564 to output 20Vpp@1.5A? customer PCB shown as attached.
[2] if we want to use 2 pieces of OPA564 in parallel to achieve 20Vpp@1.5A , do we have any reference design (schematic and PCB)?
Figure one. Chanel one as output voltage, Chanel four as output current
Figure two. Chanel one as Tflag pin voltage , Chanel four as output current, we can see OPA564 regularly went into thermal shutdown.
Best,
Luke
