Under TPS65140EVM-031 testing and make output voltage as below.
VIN : 5V
VOUT1 : 10V
VOUT2 : -6V
VOUT3 : 21V
To make a wished output voltage, modified FB resistors as below.
It works properly without LCD connection, at first. But after connecting LCD, Vo3 output voltage up to 25.3V.
After that, V03 output voltage is always 25.3V even not connecting LCD.
To make Vo3 = 21V, is there any other setting needed?
And why Vo3 output is raised to 25.3V?
Please let me get your answer ASAP.
