Hello E2E,

About how much current will be consumed by the Vdd pin in operation?

Thanks!

Hello,

The operational supply current for VDD pin is typically 17.4mA under condition:

"EN/FCCM = 5 V, PWM = 50% duty cycle, ƒsw = 500 kHz".

You may refer to the VDD section in Electrical characteristic table in the datasheet.

Please also note this IDD current may also increase with switching frequency in operation.

Best,

Qingquan

Qingquan,

Thank you for your reply. This is the link I am using for the DS:

https://www.ti.com/lit/ds/symlink/csd95491q5mc.pdf?ts=1597859117761&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FCSD95491Q5MC%253Fqgpn%253Dcsd95491q5mc

It is taken off of the product page. There is no electrical characteristic section in this DS. Is there an offline version with more data? Can you send it to me?

Hi Russell,

It requires NDA agreement for me to share. Please send email to q-tang1@ti.com.

Thanks,
