I have implemented TPS65130 application based on page 9 of TPS65130 datasheet for generating +15V and -15V.
The values of R40 and R43 are wrong, the correct values for them should be 1.2Mohm around.
I have pulled both ENP and ENN to high to enable both positive and negative power regulators.
But TPS65130 is not working since all reference voltage, output voltage are zeros.
Pin 7, BSW, is pulled to zero and Q2 is conducted but the output voltage at drain of Q2 is +3.5V instead of +5V.
Please help what are the possible reasons for this?
Thanks.
