LM5117: Current and voltage-controlled mode

TI-CSC
Genius 14080 points
Part Number: LM5117
Other Parts Discussed in Thread: LM25115, LM5115, , LM25116, LM25148

Hello E2E Experts,

Good day.

I have looked at LM5115 and LM25115, however, for our application, it will not support it.

For the requirements for our application:

1. Input voltage: 15V, Output Voltage: 13.8V and Output  current: 20A

2. Input voltage: 30V, Output Voltage: 28.6V and Output  current: 15A

 We want Parts like LM5117 but it will not meet the duty cycle.

I checked the LM25116 part. Please whether it supports? We need to control the voltage and current in our circuit (CC/CV mode).

Regards,

CSC

    Hello CSC 

    Unfortunately, both LM5117 and LM25116 do not support low dropout operation and cannot support these applications. LM25148 device supports the low dropout operation but I am not in charge of LM25148. Please create a new post and contact LM25128 Apps engineer.
