Part Number:TPS65400
Hi,
I have used TPS65400 in my design. It works well till yet as per voltage conversion. Sw1: 4.1V, SW2: 3.3V, SW3: 1.8V and SW4: 2.5V.
When I plug SOM(RPI compute module 3) then the o/p voltages get disturbed and not continuous like 4.1V varies from 1.5V to 2.5V and also other peripheral not getting operating voltages as well.
Now Problem is that 1. As i have checked(Without plugging SOM) with digital potentiometer(load) at value of 3 ohm@4.1V , I got 40mA(max. 60mA) output current while I need above 1.2A. Now what to do ??
I have also used reference circuit as per EVM , webench and other TI reference.
Please find the attached Schematic and Give your suggestions/approvals as soon as possible as it is very critical stage for us.
Thanks
Irfan
