Current Limit

[MS_19060803]

Hi all,

Could you please tell me about the maximum drain current value of MOSFET inside ICE5BR3995CZ?
The maximum current value is needed to determine the CS resister.

Hi @MS_19060803 ,

We appreciate your participation in the Infineon community.
Sorry for the delayed response.
with reference to non-isolated buck converter (Table 2) , maximum current it can handle is 550mA. This figure is selection purpose only. Actual figure vary depending on particular design. Make sure that the operation of the device is within maximum rating in chapter 4.1 of datasheet. Kindly refer the application note attached.

Hi,

Thank you for your support.

I want to know the maximum drain current value of ICE5BR3995CZ.

Is the highlight value(5.0A) correct?

Hi @MS_19060803 ,

Highlighted parameter is peak value of pulsed current.

Average current and pulsed current ratings are both a part of MOSFET ratings. Both of the parameters should be met during design. Please refer the reference design note attached in previous reply, page no. 28 for CS resistor calculation.
