Tool/software:
Good morning Mr. Shiven Dhir
this is the question you had asked me some time ago .
"
TPS2411 is rated for 16.5V. Are you trying to scale down 600V to ~12V for controller to not get damaged?
Even if it is done, the FETs will never turn-on because the GATE will be driven to ~ VA + 10V and the source of the FETs will be at 600V and VGS will be almost zero. Did I understand you correctly?
"
1)Yes exactly we want to reduce the voltage to prevent the controller from being damaged.
2) yes you got it right.Below I will describe our project.
On the advice of your colleague Jonathan Wong, starting from the UCD3138PSFBEVM-027 Evaluation Module board; we want to make a dcdc boost converter that starting from a battery voltage of 120Vdc has 600Vdc 2KW output.
Among all the modifications that need to be made , on the high voltage side,
there is of course the one concerning the TPS2411 that handles the o-ring system of the device.
Can you give us any advice on how to handle those high voltages?
thanks a lot
Gianluca
