Other Parts Discussed in Thread: TPS51113
Hi,
We are using TPS51113 for generating a voltage of 3.3V from 12V supply.
We designed our circuit in TINA and tried to simulate it but the output is not as intended. The output is below 1V.
This can be because the TPS51113 is not enabled at all. But to my knowledge it is active low enable.
Then we tried simulating the reference circuit provided by TI. It is for 1.8V output.
We tried to modify the circuit as per our requirements and still we are unable to get the output as required.
In the reference circuit, the enable is given through a switch complex and I am not aware of why it has been used.
I have attached the three .TSC files
1) circuit as per our schematic
/cfs-file/__key/communityserver-discussions-components-files/234/Circuit-schematic-design.TSC
2)reference circuit as provided by TI for 1V8
3)modified reference circuit for 3V3
We are struck at this point and any help on this would be greatly appreciated.
Regards,
Giridhar
