Hi,
I had using DRV8662 to generate 200VPP for controlling piezo load.
at no load condition for the very first time when I enable the IC it gave the o/p as is calculated vboost value of 102v
but after few minutes the vboost value going down simultaneously IC consumes more current around 300ma without any load
and also IC becomes more heat please suggest me an solution.
for you reference i attached the design files
awaiting for your replyDRV8662.rar
