Hi all
My customer has implemented a USB PD power supply with the TPS55288 with these specs:
Vin=13V
Vout= 5V ... 20V / 3A
They have used the design calculation tool and have selected these component values:
R3=27k, C7=10n und C6=330p
With these values the controller is not stable in boost mode at currents > 2.5A.
Using the values from the EVM R3=56k2, C7=4.7nF, C6 not populated the circuit works ok.
Can you comment and also review the schematic ?
They would like to optimize the compensation for Vin = 13V.
What component values should they use ?
Best regards
Ueli
