TPS55010: Inquiry about TPS55010RTER Specifications

Part Number: TPS55010

Hi,

We are currently planning to use the TPS55010RTER for generating 5V at Fsw=100kHz.

As per the datasheet, the resistance to be connected to the RT/CLK pin should be within the range of 1070kΩ to 42.2kΩ.

I have two questions regarding this:

  1. Should this value also consider the tolerance of the resistance?
  2. Is it correct to understand that the operation is not guaranteed if a resistance of more than 1070kΩ is connected?

Regards, Takumi

  • Hi Takumi,

    Here are my comments:

    1. The tolerance of the resistors should also be within the range of 1070kΩ to 42.2kΩ.

    2. Yes that's right, operation is not guaranteed more than 1070kOhm.

    Best regards,
