Part Number: TPS2121EVM-023 Other Parts Discussed in Thread: TPS2121 , , LM5116 , TPS61230 Hi TI team,
I choose TPS2121 as a power switch for my Supercap Power Backup solution. Then, I buy one set TPS2121EVM-023 for testing before releasing the schematic…
Part Number: TPS2121EVM-023 Hi Team
Would you advise that When switching the power supply with TPS2121EVM-023, a voltage drop of Vout is seen.
I think that the capacity of the capacitor is sufficient, but is it possible to eliminate this voltage drop…
Part Number: TPS2121EVM-023 Other Parts Discussed in Thread: TPS2121 , TPS2120 , TPS2115A , TPS2114A Use case:
Vin1 vs Vin2 prioritizing Vin1.
Steps to Reproduce:
1. Supply both VIN1 and VOUT with 5V
2. Disconnect supply for VIN1.
Observation:
1.VIN1 will…
Part Number: TPS2121EVM-023 Other Parts Discussed in Thread: TPS2121 Dear TI teams.
Would you like to give me advice about TPS2121.
When switching voltage, It occurs voltage drop like a pictures.
Does not occur when there is no load
Vin1 and Vin2 are 8V…
Part Number: TPS2121EVM-023 Other Parts Discussed in Thread: TPS2115A Hello Sir,
Our design is INx USB 5V, INy Li-battery 3.8(typ)
May I know how to enter standby to see standby current 25uA ?
Many thanks !
Hi Henry,
With regard to the power mux TPS2121, typically for high inductive loads or hot plug events we recommend a TVS diode to protect against voltage transients as noted in page 32 of the TPS2121 datasheet and below. However, the inductance and capacitance…
Hi Mikhail,
"Optimum resistor" values are subjective and depend on the application and the switchover behavior that is used. I highly recommend using resistors in the 10-100 Kohm range to set the voltage values at OV1,OV2,PR1 and CP2.
Looking…
Hi Kai,
Thanks for reaching out on E2E! Unfortunately DSN format is not available.
This hardware is developed in two formats : 1) Cadence concept HDL/ADW flow. 2) Altium format. This is accessible from the EVM page : www.ti.com/.../TPS2121EVM-023
Thanks, …
Part Number: TPS2121 Hello
I am evaluating about XCOMP mode using TPS2121EVM-023.
>condition Vin1=3.3V Vin2=5.0V
When Vin1 falls dramatically(fall time < 1ms) , Vout rises to 5 V after becoming 0 V.
> Vout : 3.3V -> 0V -> 5V
But When Vin1…

Hi team,
I'm checking about Input channel selection and ST pin with TPS2121EVM-023.
Fig.1 is my circuit and Fig.2 is my environment.
I operated that IN2 was valid after IN1 was valid.
I guessed the IN2 was selected and ST was…
