TPS65149: VGL is noisy and oscillates when loaded.

Stan Searing

Part Number: TPS65149

Under light load there is noise around 5 kHz. At about 10 mA load VGL goes into large oscillations. Suggestions?

Hi Stan,

Could you please send me the schematic for double check? You could send me through private message if you have confidential concern.
