TPS54560: Split-Rail, Problems generating +-15V from Vin 24V

Part Number: TPS54560

Tool/software:

Hello,

As shown in the schematics below, I am trying to generate +-15V using split rail configurations from TPS54560. The circuit behaves weirdly by drawing too much current without any signs of correct output voltages. Am I doing something wrong with the component values i.e too large output capacitance value? I 

Tested with two different coupled Inductors: 
YPRH1207C-150M
SRF1280-150M

Please let me know if more information is needed.


Any help or guidance is greatly appreciated. Thanks!

  • Hello Qais

    Please measure VIN, IIN, VOUT and IOUT when you think the circuit behaves weirdly by drawing too much current, and let me know the measurement results. 

    Also, please capture some waveforms for more investigation.
