Hi everyone,
TPS65286 is a dual power switches with integrated buck converter.
I only want to test the efficiency of integrated buck (from 20V to 15V, light load to 6A).
So I first disable the power switches (JP2 and 3) and remove JP1 and 7.
Second, I change the divider to output 15V, R1 = 152k ohm, R2 = 6.34k ohm.
There is only 13V on output CAP after powering up EVM (no connect to load).
I try to measure again, the voltage drop to zero.
EN pin still high, FB pin become low rather than 0.6V.
I change a new IC and resistor divider to output 5V, now the EVM is normal.
Because datasheet don't mention the output voltage range, I want to know:
1. If TPS65286 can convert from 20V to 15V and support up to 6A or not?
2. if it can, what can I do next step?
Best Regards,
Allen Lee
