Good morning

sorry if I post this reply here I know it is not the right blog because it is about TPS2411 but I don't know how to go about answering the question of “Shiven Dhir” since more than a month has passed.

Could you please redirect it to the right tread?

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
