TPS43060: The range of resistance value of connecting VCC

Shinichi Inoue

Part Number: TPS43060

Dear Specialists,

My customer is considering TPS43060 and has a question .

I would be grateful if you could advise.

---

According to the datasheet P.12 8.3.13 Gate Drivers, resistance of connecting Vcc pin is required 2ohm, what is the range of resistance value.

For example, is it possible to use 2.2ohm?

Because 2.2ohm is more affordable than 2ohm.

What percent is required the resistance accuracy.

I appreciate your great help in advance.

Best regards,

Shinichi

    Thank you for considering the TPS43060. The 2Ohm resistor is just a guideline and you can use 2.2Ohm or higher unless your efficiency is not reduced too much. There is not special accuracy requirement for this resistor.

    Hi Youhao,

    Thank you for your reply.

    I understand the resister of connecting Vcc series can use 2.2ohm and doesn't have any accuracy requirement.

    I'll share your answer with the customer.

    I appreciate your great help.

    Best regards,

    Shinichi
