Hi Eddie,

Thanks for reaching out. The resistor is not a must requriement.

(1) If no EN signal, you can use a top resistor and bottom resistor for EN.

(2) Another way is to have EN signal to control (<5.5V).

Thanks and kindly let us know anything unclear!

Hi Lucia and Expert,

If i do not have EN control and need it , Can i just let the EN pin keep flat ?

Do I see any risk in here ?

Hi Eddie,

Could you please clarify "let EN keep flat"? Do you mean floating EN pin?

Thanks!

Hi Eddie,

If you mean EN pin floating, it can not enable the device. TPS563252/7 EN default is low which means that if it's floating it will not enabled. TPS562242 (2A) default status is high if you would like to make EN floating.

Thanks!
