Part Number: TPS2121 Tool/software: Dear experts,
We're currently in the process of designing a new iteration of one of our products. The behaviour should be as follows;
Only if a USB-PD adapter that is supplying 12V (or more than 11V) is connected…
Hi Sandra,
I think this is not related to MUX because MUX can not affect VIN. Due to loading of DC-DC VIN is getting affected and we are seeing same behavior at output as VIN is not stable.

Part Number: TPS2121 Tool/software: Hello,
The voltage at IN1 is 5V, and the voltage at IN2 is 4.2V. During switching, I observed that the output voltage drops momentarily and then returns to normal after a certain period.
I believe that if the switching…
Part Number: TPS2121 Tool/software: Hi Team,
There's a new design with TPS2121. 12Vin is the main power and 12VSB is backup power. When powerup, 12VSB is always on and 12Vin enabled by MCU.The shcematic is like below,
Please help us to review it…
Hi SWE,
Sorry for delay. Drop is due to delay between VIN2 and CP2. CP2 should be connected through resistor divider to VIN2.
Fast-switchover only happens when CP2 is high.
