Part Number: TPS65020 Tool/software: I am using all 3 converters on this part. While DCDC1 and DCDC3 turn on once their respective EN pins reach ~1.15V, the DCDC2 output turns on when its EN pin is at ~700mV. I realize that technically this might be considered…
Part Number: TPS65020 Hi team.
Customer found an issue during powering up. SCH is as below. And during power up, we found that the PWM will interrupt sometimes which cause the glitch of power up. Blue waveform is VDCDC2 and yellow waveform is PWM waveform…

Thanks, we confirm it is TPS65020, a general PMIC and use the EN for the sequence control, so if DCDC1 is not enable, will other rail have some leakage to this rail? we would like to confirm it in EVM. thanks for your help.

Hi
Got the below question:
I have the TPS650250EVM.
I soldered resistors (R12=56.2k,R1=48.7k) to set VDCDC1 output to 1.12v
I measured these output voltages at 1.6A load:
Vin=3.30v -> Vout=1.126v
Vin=5.00v -> Vout=1.118v
Results are OK…
Other Parts Discussed in Thread: TPS65020 , OMAP3503 , TPS65920 Hi,
Can TPS65020 be used to power up an OMAP3503? I am looking for a PMIC solution that will not need a 32KHz to start up.
Thanks,
Danny
Hello Richard,
Thank you very much, I needed your confirmation.
But I noticed TPS65020/021/022 are not (yet) marked as NRND. What can you say about using one of them instead of the LP3972? Is the software differs from the LP3970 too large? Would you…
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…
Saqib,
As you mentioned offline, the input voltage is 24V and we are assuming there is a 12V rail in the system.
Since the current requirements are low, I will recommend the TPS65020 (1A max on DCDC1) instead of the TPS65023 (1.7A Max on DCDC1)…
Hi Randhir,
Based on previous experience, the TPS6502x family is a good match for the SAMA5D2 family. Depending on their requirements, this can mean the TPS65020, TPS650250, or TPS65023 would all be good fits.
Here is a previous E2E post on the…
