HI,
im using TPS65146( IC LCD supply TFT 24-VQFN) to provide required supply voltages to run 7 inch LCD panel so i used a 24-VQFN breakout board with IC ready assembled and i just added the discreet components, but unfortunately it did not work and the VS out that i got was the same as input (3.3V) instead of 10.4v,and all other voltage were also nither 3.3v or less, so please advice what is the problem and how to troubleshoot it, following is the schematic I've used:
knowing that the required supply voltages are:
1. VGH=16V
2. VGL = -7V
3. VS = 10.4
4. VCOM = 3.8V
thanks in advance
