POWER ON / OFF issues

Other Parts Discussed in Thread: TPS65020

Hello Ti,

We are using tps65020 IC is using for our board to handle the power management. The problem is; When we POWER ON and POWER OFF continuously [with 1sec delay], Sufficient PMIC output VRTC is not coming properly. ie, our board required 3.3V from VRTC pin of tps65020 at normal condition to enable the processor, but when we POWER ON and POWER OFF continuously, sometimes 2.9V is coming instead of 3.3V. So the processor not enabling. Hence board is not working. Please suggest that, why VRTC is not coming properly when POWER ON and POWER OFF continuously ?

Regards,

Azlum
