Original question:
Tool/software:
Hi support all.
The LM5168 seems to be able to generate -80V from 24V, but the output current cannot achieve 130mA.
Can you suggest a product that can meet this requirement?
An additional requirement is that no transformers are allowed.
Best regards,
Higa
Hi Higa,
Note that output current in IBB mode is reduced by a factor (1-effcetive duty) as shown below
There is a higher current variant also LM5169 data sheet, product information and support | TI.com but here also the maximum possible IBB current might not be sufficient for the required output. what is maximum Vout?
You can use the fly-buck configuration for this.

Arpita
