Part Number: LM5116 Within the Functional Block Diagram, it shows the UVLO pin 2 being pulled up by a 5uA current source to 1.215V, but the UVLO threshold to enable the LM5116 is 1.215V nominal and 1.262 max. So if the UVLO pin is left open and the internal…

Hello EricLee,
Many thanks for your reply.
If I change some components with 25% ripple current and VCCX to zero based on LM5116 quick start ( selected components), can I reach to a suitable result?
Thanks again, Leila

Part Number: LM5116 Hello,
Based on the TI user guide for PCB stack-up designing for LM5116( www.ti.com/.../snva285) I defined 4 layers of PCB for it with these features (2-ounce copper top and bottom, 1-ounce copper internal layers on FR4 material with…

Part Number: LM5116 I have used a LM5116 chip to design a synchronous buck converter with a fixed voltage output at varying input from 12 to 75 volts. When in no load condition circuit performs well i.e. it gives a fixed output voltage of 5V. However…
Part Number: LM5116 Other Parts Discussed in Thread: LM25149 , Hello,
Thanks a lot for introducing LM5116 instead of LM25149.
I want to design a buck converter with 54V input and 24V and 3.5A as output . I could design it based on the quick start calculator…
Part Number: LM5116-HT I have a 60V power supply using the LM5116HJD. I'm currently using diode emulation mode, but I'm wondering if its better not too? Efficiency at lower power is not a big concern.
I am using a sense resistor (not trying to…
