TPS82130: Solution for 3.3V to -3.3V high output current negative inverting

Part Number: TPS82130
Other Parts Discussed in Thread: TPS62135

Hi Team,

Our customer is looking for small package 3.3V to -3.3V with >1.5A high output current negative inverting solutions, and we tested TPS82130/TPS62135 for inverting circuit based on EVM, but it looks like it can not handle this condition, please refer to below results. Can you help to check if we have any other better solutions?

Customer requirements:

1. Input voltage: +3.3V(may vary from 2.7V~3.4V).

2. Output voltage: -3.3V±0.1V, 1.5A~2A load.

3. Small solution size and package.

Our TPS82130/TPS62135 EVM test results:
