LM5166: Adjustable Current Limit Thresholds

Expert 3791 points
Part Number: LM5166
Other Parts Discussed in Thread: TPS54060

Hello TI Team,

I have a customer that is currently using the TPS54060 on a current design, and they are considering making the change to the LM5166 since it has the adjustable current limit. 

Unfortunately, it appears as though the current limit they want to set does not fall within the set thresholds provided in Section 7.3.5 of the datasheet.  

Is there a way to use external passive circuitry to set the current limit within the set thresholds of 200mA, 300mA and 500mA? 

They need the wide input range up to 60V so we are limited on our options for wide-vin DC/DC converters with adjustable current limit. There is always the option of using an active circuit to set this limit, but I'd like to see if we can accomplish this using the LM5166.

Thank you for you help in advance!

Best Regards,

Javier Palomo
