TPS65251: Power good is not asserted while using two outputs in triple output power supply

Part Number: TPS65251

As per our requirement, we are using two outputs of TPS65251. Buck 1 : 3.3V & Buck 2 : 1.2V.and PGOOD for power status in our design.

Buck 3 is properly disabled by pulling low to the EN3 pin,

Even though we are disabling Buck 3 ,, Buck 1, Buck 2 output voltages are in desired range, the PGOOD is not de asserted.

Please support us
