Part Number: TPS25942A

Hi,

Let's me talk about unused pins of TPS25942A.
Customer does not use the PGOOD pin.
In that case,
Could tell me the recommended pin treatment of PGTH pin and PGOOD pin?

Hi Yusuke,

PGOOD can be left open or tied to GND when not used
and PGTH pin can be connected to GND

Best Regards

Rakesh-san,

Thank you for your support.
Is there a recommended value for pull-down resistor?
Or may I connect directly to GND?
