TPS65131: Request for Schematic Review

Part Number: TPS65131

Tool/software:

The purpose of this design is to supply clean +12V and -12V for op-amp operations.

The circuit initially steps up 5V to ±14V, then uses LDOs to regulate the output to ±12V.

For +12V, the TLV1117I is used, and for -12V, the TPS7A3001 is used.

Please let me know of any questions.

Regards,

Andrew
