TPS54225: TPS54225 PG pin pull-up resistor

Mason Liu

Part Number: TPS54225

Hi,

Our datasheet says PG pin should pull up to VREG5, with 20K - 150K ohm resistor, is there any risk if using 4.7K resistor, pull up to 4.7V?

Thanks.

Hi Mason,

I did not find a max value in the datasheet but since the sink current of 1mA (4.7V/4.7k) is even lower than the typical(5mA), it should be fine to use a 4.7kohm resistor to 4.7V.

Thanks,

Amod
