ADP5073 can't provide current according to specification

Category: Choose a category
Product Number: ADP5073

Hello,

In the selection table for inverting regulator it's specified that ADP5073 can deliver 1.375A.

Here is simulation setup where I check its capability to generate -30V from +5V.

The values of Rfb, Rft, L1, etc. I took from datasheet hint table.

I tried with two loads - 1k and 100Ohm

1k - Ok, whereas 100 Ohm failed.

Any comments ?

Thanks.

Refer to this table below on what the maximum output current it is able to output depending on the input voltage output voltage ratio. This can be found on the datasheet page 7. ADP5073 (Rev. A) (analog.com)
