TPS543320: MODE pin resistor

Allen Wachter

Part Number: TPS543320

Targeted MODE resistor is 243k. Is it OK to use a 249k? Is there a tolerance value associated with these resistors?

Thanks!

Hi Allen,

No, you could not use 249k for 243k as MODE resistor. It is required to use 1 % tolerance resistor or better in datasheet section 7.3.8 Mode Pin.

Hope this helps,

Thanks,

Nancy
