Part Number: TPS2121 Dear Sir,
I have a project that uses TPS2121RUXR to switch between two power sources (USB and Li-ion battery).
The output of TPS2121 is connected to two 100uF/10V/X5R and one 0.1uF/10V/X7R MLCC, and then connected to the Buck and…
Part Number: TPS2121 Hi, I am using TPS2121 in our design with the following parameters: VIN1 = DC Adaptor = 5V , VIN 2 = VBUS = Regulated voltage range 4.75~5.25V. Now , CP2 voltage=1.8V, PR1= 1.3V
Now , i have a problem. When adaptor and USB power are existing…
Part Number: TPS2121 Please review the schematic and resistor settings for TPS2121 and provide the feedback. The resistor calculation also attached below.
Both inputs are 20V, Input1 is DOCK station and Input2 is from VBUS (USBC). The default power path…
Part Number: TPS2121 Hello Guys,
Our customer have a few queries on TPS2121 Power Mux.
1. What is the purpose of having a capacitor and resistor at VOUT? Will that reduce the output voltage? 2. If i want the highest input to be at VOUT, meaning…
Part Number: TPS2121 Hi team,
Regarding the switchover time of TPS2121, in the case of XCOMP mode, it is stated in the data sheet that the power is switched in 5us by Fast Switchover Control. In the case of VCOMP mode, what is the switchover time? (If the…
Part Number: TPS2121 Other Parts Discussed in Thread: TPS2120 , TPS25947 I likely will need a little more than the 4 to 5A offered by a TPS2121. 6A should do it.
Can I put two TPS2121 or TPS2120 in parallel and tie the outputs together?
Note: My two…
Part Number: TPS2121 HI Expert,
Here is system power flow. POE 12V > TPS2121
There are many capacitor between POE and TPS2121. Around 600uF.
I want to calculate the inrush current from POE output side to TPS2121.
Where can check the TPS2121 internal…
Part Number: TPS2121 Hi Expert,
Here is power flow. POE 12V> TPS2121
we have around 600uF from POE 12V output to TPS2121 input.
Could I know how to calculated inrush current? And where can I check the internal FET SOA of TPS2121.
