Part Number: TPS61378-Q1
Hello, I'm using TPS61378-Q1 to get 6V from 3,7V. The device works good, it outputs 6V but when I add a load (6V DC motor), the output falls.
The schematic I'm using is the following:
U3 is another regulator, but it is not placed in the board.
The thing is, I have another board, with the same schematic and parts placed, with the only difference that the TPS is the TPS613785-Q1, and this one works when the load is placed.
This pic shows the output fall (yellow) when the load is connected. Purple is VIN.
The following pic shows the behavour of the board with the TPS613785-Q1:
It falls, but then recovers, getting this curves that I actually don't understand too much.
Can anyone help me with this? I'm not able to detect the problem which causes the output to fall when adding the load.
Thank you very much!
Pablo
