Part Number: LM5146-Q1 Other Parts Discussed in Thread: LM5146 , LM5164-Q1 Hi everyone!
I've designed a buck converter based on LM5146 IC using webench design. Also I checked the design with the quick start calculator. Input voltage is 15v < Vin < 95v and…

Hi,
The converter is designed for an input voltage of 50V-84V and an output current of 10A.
When we give a supply of 70V, the converter is making a ticking sound, and output voltage varies…
Part Number: LM5146-Q1 Other Parts Discussed in Thread: LM5145 Hi Team,
Our customer simulated the LM5146QRGYRQ1 in Webench. Below is the link to the simulation.

Hello. I have a problem with LM5146 controller on my board. It`s temperature is 100C! Vin=56V, Vout=12V, I load = 0.3A. Tell me please how can i fix that?
I have attached…
Part Number: LM5146-Q1 Other Parts Discussed in Thread: LM5146 , LM5069 Hi there
I am facing an issue with the LM5146 buck. I am using it for a 58V to 12V 5A application.
When the input of "58V" is given to the buck through a two pin connector, a huge transience…

Hi I am using LM5146QRGYRQ1 to generate 5v 2A . I used the help of the Power designer to generate a schematic.
1. In the following design across Cin, I see quantity = 5 , what does…
Part Number: LM5146-Q1 Other Parts Discussed in Thread: LM5146 Hi,
I've got a problem with one of the designs based on LM5146. All seems to function correctly except for quite high input current as for no load (it consumes roughly 50-60 mA of current depending…
Hi Dinesh,
See app note snva829 for more detail on constant current limitation using an output shunt.
https://www.ti.com/lit/an/snva829/snva829.pdf
The LM5146-Q1 also provides current limiting but will enter hiccup and restart if an OCP condition occurs…

Hi team
Could you tell the the difference between standby mode and shut down mode?
And could you also tell when to use each mode?
Customer wants to use the device in shut down mode in their…
